An Outline of the History of Restriction on
Ijtihad by Shaykh Aga Buzurg Tehrani
Translated from the Arabic by Mujahid Husayn
The original in Arabic appeared under the title Ta'rikh hasr al-ijtihad (Qumm: Matba'at al-Khayyam, 1401 A.H), a publication of Madrasat al-Imam al Mahdi ('a), Khunsar, and edited by Muhammad 'Ali al-Ansari al-Shushtari. Muhammad Muhsin Aqa Buzurg Tehrani (1293-1389/1876-1969), the author of al-Dhari'ah ila tasanif al-Shi'ah, the well-known bibliographical book on works written by Shi'i authors from the earliest times to the contemporary era, was an eminent contemporary scholar. His other writings include, Tabaqat a'lam al-Shi'ah (a biographical work on eminent Shi'i scholars from the 4th/10th to the 14th/20th century), Musaff a al-maqal fi musannifi 'ilm al-rijal (accounts of about 500 Shi'i scholars who have written on 'ilm al-rijal), Hadiyyat al-razi ila almujaddid al-Shirazi (a biography of al-Mirza Muhammad Hasan al-Shirazi, well known for his famous fatwa against the granting of monopoly rights on tobacco trade to a British company by Nasir al-Din Shah, the Qajar ruler), al-Naqd al-latif fi nafy al-tahrif 'an al-Qur'an a-sharif (on refutation of tahrif in the Qur'an), and Taf nid qawl al-awam bi qidam al-kalam (dealing with the well-known theological controversy between the Mu'tazilites and the Ash'arites concerning the eternity of the Qur'an). The editor of the Arabic text has written footnotes, most of which that were relevant to a translation have been retained here as endnotes.
Al-Sayyid Ja'far ibn al-Sayyid Hasan al-A'raji al-Musili, learned, felicitous, pious, and excellent, may God grant you a long life dedicated to the revival of the Law of your most immaculate ancestor-you have asked me to write something describing the causes of the differences of the Sunni legal schools (madhahib al' ammah) concerning religious law (furu' ahkam al-din), the emergence of the four schools, the reasons of their adoption to the exclusion of other schools, the history of events leading to their exclusive recognition, the reasons behind the difference of opinion amongst Shi'i 'ulama' in many legal issues, and the history of emergence of the Shi'i school of law.
In responding to your request I say: To be certain the eminent amongst the scholars of the Ummah have written books and treatises on these issues in the past. Therein they have recorded its history as it had reached them, explaining amply the causes of these differences as disclosed by authentic sources and in a manner acceptable to reason, so as to remove almost all doubts and misconceptions by making manifest the truth like a shining torch for one and all.
However, as these books contain what appear to be signs of sectarian bias, which largely inspired the polemics of those times, these explanations fail to have the desired effect in cutting the roots of controversy and ushering in the spirit of harmony and accord.
However, in this age of enlightenment and brilliance, radiant with the light of knowledge, and freedom from the bondage of imitation based upon ignorance, we and our correligionists are hopeful that God, the Exalted, would grant us success in abandoning sterile bias and blameworthy imitation, so that the truth becomes manifest for us like the light on Mount Sinai through this treatise Tawdih al-rashad fi ta'rikh hasr al-ijtihad that I intend to set before our brethren, may God grant them success in reflecting over these words, which contain a reminder for the servants of God to remove restrictions on the practice of ijtihad. I do not write except with the aim to reveal the truth, and
I desire only to set things right, so far as I am able. My success is only with God. (11:88)
The Beginning of Disagreement Amongst
There is no doubt that disagreement among Muslims in the sphere of religious law (furu' al-din) began only after the Prophet's (s) demise and not in his lifetime. The whole Ummah used to seek guidance from the light of his sciences in all the spheres and without the temerity to present any opinion in opposition to him, because that would have violated their affirmation [of the Qur'anic statement concerning him] that:
He speaks not out of caprice. (53:3)
Hence al-Maqrizi's statement that "the ten (Companions) who were given the good tidings of paradise (al-asharah al-mubashsharah) used to issue fatwas during the lifetime of the Prophet (s)",  suggesting an early emergence of ijtihad and the practice of issuing fatwa, underrates the station of the Prophet (s) and is derogatory to these Companions, for their mere faith did not permit them to do so, except when they were ordered to do so by the Prophet (s), and that too not in opposition to him.
Similarly, there is no doubt that legal issues (furu') were not the subject of the first controversy that occurred in Islam. All historical accounts agree that the first difference to occur amongst Muslims following the death of the Prophet (s) and prior to his burial wits concerning the issue of khilafah and wilayah.
This disagreement also did not exist during the lifetime of the Prophet (s), since not a single history mentions it. On the contrary, while the Prophet (s) was alive all the Muslims concurred with the order of their Prophet in taking the oath of allegiance (bay'ah) to his cousin on the day of Ghadir, with all the details mentioned in all the books of history and sirah?  Hence, while he was alive they acknowledged the wilayah (guardianship), wizarah (vaziership), wisayah (trusteeship), khilafah (vicegerency), and imamah (leadership) of his cousin, in accordance with the explicit statements of the Prophet (s) regarding all these matters on various occasions from the time of his bi'thah (beginning of his ministry) in Makkah to the time of his demise in Madinah. During this span of time, not a single voice of dissent was ever heard from among the Companions. 
There is again no doubt that after the demise of the Prophet (s) the Ummah in its entirety was not unanimous about the khilafah of a particular person from the community. Rather, immediately after the Prophet's demise, some persons of the community took the lead in breaking the oath of allegiance taken at Ghadir and initiated the rejection of wilayah. This rejection and dissidence spread gradually to others. Thereafter the affair of the khilafah was decided as a result of the efforts of some prominent persons of the Muslim community who preoccupied themselves with directing the matter of succession and nomination of another person to the office, making arrangements that lead to the formation of a majority from numerous groups within a few days.
Following the controversy among prominent persons from among the Muhajirun and the Ansar, as well as others, the outcome was a split into two groups: the Shi'ah (Khassah) and the generality of people ('Ammah). The Khassah was the group which remained with the Wasi (i.e. 'Ali ['a]) and loyal to his wilayah. The 'Ammah were those who distanced themselves from him. This was beginning of the difference.
Then the minority group which remained loyal to the bay'ah of the Wasi, acknowledged his title to the Imamah, and believed in his infallibility ('ismah) and obedience to him as a duty ordained by God, the Exalted, considered it binding upon itself to follow him in religious precepts (al-ahkam al-diniyyah) which God had conveyed to His prophet and which the latter had entrusted to his wasi, confiding all of them to him while proclaiming to the people:
I am the city of Divine knowledge and 'Ali is its gateway. 
This group took recourse in him for guidance in all religious matters in all their detail, learning and committing to writing the precepts and teachings of their Imam who had been designated by God, the Exalted, and was preserved against any kind of error. Thus they recorded from each Imam, infallible and designated by the preceding imam, one after another, up to the Master of the Age in occultation, may God's blessings be upon all of them.
This group of Muslims adhered to the thaqalayn (lit. 'two precious things') from God, the Exalted, which their prophet (s) had left behind for his ummah. These two are, the Book of God and the Household of the Prophet (s), which 'will not separate from each other until they meet him (s) at the Pool' , as has been narrated in a large number of traditions recorded by both Sunni and the Shi'i traditionists.  The motto of this group is 'following' (tashayyu'), because they follow 'Ali, may peace be upon him, and the Imams of his descent, relying on none except the Ahl al-Bayt, may peace be upon them, unaffiliated with any of the schools of fiqh.
They are known as "Ja'fari" not because Ja'far ibn Muhammad, may peace be upon him, is an imam of only this school, but because during his lifetime the ruling regimes, that of the Umayyads and the `Abbassids, were weak and preoccupied with their own problems, and this gave the Shi'ah a respite which they used fully to acquire the knowledge of the ahkam (laws) and other teachings from their Imam. Thus the propagation of the madhhab (school of law) of the Ahl al-Bayt and widening of the circle of its influence during the lifetime of Imam Abu `Abd Allah Ja'far ibn Muhammad al-Sadiq, may peace be upon him, resulted in the Shi'ah being identified by ,his name, though the qualification "Ja'fari" is sometimes also used to distinguish them from Zaydi Shi`is.
Summarily, the Shi'ah do not submit to anything whatsoever except the Book of God, the Exalted, and the Sunnah of His prophet as received from the Imams of his Household, who are secure from error and lapse. This has been their custom since the time of the demise of the Prophet, may God bless him and his Household, to the present day. They act as per the literary meanings of the Holy Qur'an and its unambiguous verses (muhkamat), and refer the verses standing in need of interpretation (mutashabihat) to the Imams. They follow the Sunnah of the Prophet (s) as narrated through reliable chains of transmission from the Infallible Household and compiled in books and the `usul' (early collections of Shi`i hadith) which are extant to this day either in their original form or with their contents rearranged in chapters, as explained in detail in the introduction of our book al-Dhari'ah. 
The Continuity, Meaning, and Legal
Significance of Ijtihad in the Imami Shi'i Tradition:
The Shi`i ulama', in all the eras, have applied ijtihad for understanding the literal meanings of the Holy Qur'an and the Sunnah, in the sense that they have been deriving religious laws from these two sources by applying specific rules of deduction. However, in the early period the prerequisites of ijtihad were few and its method was simple, and it was possible for even ordinary people, to say nothing of the learned and the elect, to attain the knowledge of divine laws by practising ijtihad.
But later, with the passage of time and after the era of the Imams and the beginning of the ghaybah (Occultation), and the vicissitudes faced by the books and the usul and their compilers, with the dispersion of manuscripts in different parts of the world along with its natural consequences in the form of differences resulting from discrepancies and lapses committed due to error or forgetfulness of copyists and editors, despite their credibility and care in recording-all this contributed to the proliferation of the prerequisites of ijtihad. Its acquisition came to require, the study of a number of sciences relevant to understanding the texts and literal meanings of the Qur'an and the Sunnah and to determining the authenticity of the narrators and the chains of transmission for distinguishing the authentic from the faulty and the praiseworthy from the blameworthy, among other things.
Moreover, the practice of ijtihad in the sense of making full effort for deriving the rules of the Shari'ah and determining the import of the texts and the credibility of chains of transmission of traditions-is the obligation of every capable individual (wajib'ayni) in the opinion of all Shi'i scholars and if an adequate number of persons do not meet it, all other mukallaf individuals are obliged to fulfil it. But if others are performing this duty to an adequate extent, the rest are relieved of the, obligation.
That which we have mentioned regarding the consensus of Shi'i 'Ulama' concerning the obligation of ijtihad in deducing religious laws is true of, their actual practice, though some later scholars have verbally disavowed it on the claim of acting according to the traditions (akhbar). They are therefore known as Akhbaris. But we have explained elsewhere that this is only a verbal dispute, because one cannot act in accordance with traditions without acting according to their meanings as understood and interpreted. Hence acting on a tradition depends on comprehending its meaning and purport, and we do not imply by ijtihad anything except the derivation of the meanings of traditions and deduction therefrom,? and this is something common to all Shi'i 'ulama'.
It is a fact that all Shi'i 'ulama' reject `ijtihad' in the sense of acting and issuing fatwa (legal opinion; pl. fatawa) on the basis of ra'y (subjective judgment), istihsan and qiyas (analogical reasoning), a which are prevalent among the Ahl al-Sunnah and considered valid by them. This position is based on what has been received from their Imams, may peace be upon them, concerning the invalidity of qiyas and the unreliability of ra'y and istihsan. Hence, ijtihad in this sense is invalid in their opinion, so much so that the works of Ibn al-Junayd, one of their earliest fuqaha' and one of the two earliest among them, have been set aside because he has been accused of practising qiyas. 
The Causes of Variant Fatawa:
From what we have mentioned, the reason behind differences of opinion among Shi' 'ulama' themselves regarding issues of law becomes obvious. Its basic cause lies in either the different opinions regarding the acceptability of a particular text, or the degree to which it is found convincing by someone, or the different degrees of sharpness, intelligence and perspicacity of minds in dealing with the issues and the texts involved.
Ijtihad Among the Ahl al-Sunnah:
As to the other Muslims who retracted from the oath of allegiance to Amir al-Mu'minin `Ali, may peace be upon him, they came to hold that the Prophet, may God bless him and his Household, neither appointed any successor nor made any will for anyone to exercise wilayah over Muslims after his demise. Indeed [they maintain] he refrained from making any will in order to leave the community fully free to determine a successor and ruler itself. Hence it may choose from among the community any person it desires and concurs upon.
Similarly, [they held that] he designated no specific person as an authority in matters of the law of Islam. Rather, he left [the exposition of] the Islamic Shari'ah after himself to the generality of his contemporaries (ashab) because all of them possessed the quality of `adalah  (credibility) and the capacity for ijtihad, alleging that [the Prophet had declared]:  (`My Companions are like stars, you will be guided if you follow anyone of them').
Consequently, for these Muslims the basis of practice in matters of law was the authority of the Companions and their fatwds, irrespective of whether the fatwa was based on a tradition of the Prophet, may peace and God's blessings be upon him and his Household, which the Companion had heard from him or was the result of his own ijtihad and ra'y. This was so because the Companions were considered unerring (musiban) in their ijtihad, as is elucidated in their books on jurisprudence (usul).
It is not our present concern to debate the validity of these claims or to provide a proof that this tradition is a forgery ascribed to the Prophet, may peace and God's blessings be upon him and his Household. In this regard, the 'Allamah of India [Mir Hamid Husayn], in the second of the two volumes of his book 'Abaqat al-anwar on Hadith al-Thaqalayn, in some 250 large-size pages of his book where he cites many evidences from the works of some most eminent Sunni 'ulama' who affirm its fabricated character, has cited seventy reasons invalidating the tradition. This study may be referred to on this issue whose elaboration is outside the scope of our discussion about restriction on the number of schools of law and the question pertaining to it.
Sources on the Beginnings of
Proliferation of the Schools:
Answers to the issues pertinent to this question become obvious on referring to many books of the Ahl al-Sunnah-some of which we shall mention by the way of a general guidance regarding sources-where these answers can be found and from which we shall be giving citations.
Among these books is al-Mawa'iz wa al-i'tibar fi al-khutat wa al-athar, a comprehensive popular work on Egyptian history, by al-Shaykh Taqi al-Din Abu al-'Abbas Ahmad ibn Ali ibn 'Abd al-Qadir ibn Muhammad al-Bali al-Qahiri, popularly known as al-Maqrizi, a nisbah relating to a quarter of Ba'labak known as al-Maqarizah, where he was born in 766/1364 and died in Cairo in 845/1441. It has been published a number of times, complete and in parts, and has been translated into French. It is relied upon and accepted by all later authors who cite what he mentions as an established fact. In this book (vol. 4, p. 141 ff.) al-Maqrizi has dealt elaborately with differences among the schools of law, devoting several pages to the topic under the heading "Dhikr madhahib ahl Misr wa nihalihim mundhu iftataha 'Umar ibn al-'As ila an saru ila i'tiqad al-madhahib al-arba'ah" ('Discussion of the legal sects and creeds of the people of Egypt from the time of 'Umar ibn al-'As' conquest up to their acceptance of the four schools of law'). 
Another source is the history of al-Ya'qubi, Ahmad ibn Abi Ya'qub al-Baghdadi (d. after 296/908), and printed in Najaf in 1358 H.
Another source is al-Hawadith al-jami'ah fi al-mi'at al-sabi'ah of Kamal al-Din 'Abd al-Razzaq ibn al-Marwazi al-Fuwati al-Baghdadi (d. 723/1323), printed in Baghdad at Matba'at al-Furat in 1351 H. It mentions some points to which we will refer at an appropriate place.
Among the sources are al-Insaf fi bayan sabab al-ikhtilaf and 'Aqd al-jid fi ahkam al-ijtihad wa al-taqlid. These two are the works of Shah Wali Allah Ahmad ibn 'Abd al-Rahim al-'Umari al-Dehlawi (b. 1114/1702; d. 1180/1766 .or 1176/1762). Both have been printed together with al-Muqabasat of Abu Hayyan al-Tawhidi, as well as with Kashf al-zur wa al-buhtan. 
Other sources are al-Iqlid li adillat al-ijtihad wa al-taqlid and al-Tariqat al-muthla fi al-isharah ila tark al-taqlid, both by Siddiq Hasan Khan al-Qannawji al-Bukhari (d. 1308/1890), both printed at Astanah in 1295 and 1296 H. There is another book of his called Husul al-ma'mul min 'ilm al-usul, which has been published in al-Jawa'ib in 1296 H. its "almaqsad al-thalith" (sic)  deals with ijtihad and taqlid and is the last of three books published together in one volume, the first two being Luqtat al-ajlan fi ma tamussu ila ma'rifathihi hajat al-insan and Khabi'at al-akwan fi iftiraq al-umam 'ala al-madhahib wa al-adyan.
There is also the article of the author of al-Sa'adah, Ahmad Taymur Basha ibn Isma'il ibn Muhammad (b. 1288/1871 at Cairo), entitled "Nazrah ta'rikhiyyah fi huduth al- madhahib al-arba'ah," published in the magazine al-Zahra' at the beginning of its second year and later printed separately in Cairo by Muhibb al-Din al-Khatib on 15th Rajab 1344 H. He has described in this article the causes of the birth of the four schools of law, the places where they initially emerged, the mode of their growth and spread to other points, and a brief historical account of the extinct schools from the time of their emergence, their gradual spread and the extent of their currency until their eventual extinction.
The most detailed study of this issue among the sources mentioned is that of the learned Muhammad Farid Wajdi Beg (b. 1293/1876) in the third volume of the Da'irat al-ma'arif fi al-qarn al-rabi' 'ashar al-hijri,  published in 1330 H. His discussion on the subject, under the root j-h-d, covers sixty pages. There he reproduces the two books mentioned earlier in their entirety, i.e. al-Insaf fi bayan sabab al-ikhtilaf and 'Iqd al-jid. He has also discussed the issue at length under the root dh-h-b, referring here to what he has already mentioned under j-h-d.
These are the books that were accessible to me on this subject, and Siddiq Hasan Khan, in the third "maqsad"  of his book Husul al-ma'mul, mentions some other works in this regard asking the reader to refer to them. Of these are:
Adab al-talab wa muntaha al-irab by al-Shawkani,
Irshad al-naqqad ila taysir al-ijtihad by al-Sayyid Muhammad ibn Isma`il al-Amir,
I'lam al-mawqa'in 'an rabb al-'alamin by al-Hafiz Ibn al-Qayyim,
Iqaz himam uli al-absar fi al-iqtida' bi sayyid al-muhaijrina wa al-ansar] by al-Fullani, Salih ibn Muhammad (printed),
al-Jannah fi al-uswat al-hasanah bi al-sunnah (which he mentions among his own works),
Dirasat al-labib fi al-uswat al-hasanah bi al-habib by al-`Allamah Muhammad Win al-Sindi,
Muhammad al-adhkiya' by al-Sayyid Ahmad Hasan al-Qannawji,
al-Qawl al-mufid fi hukm al-taqlid, and other books written on ijtihad and taqlid.
Since the books I have mentioned here may be either inaccessible to our Sayyid or he may not have the time to refer to them and find the relevant parts, I shall give here a summary of their contents to the extent of providing a concise answer to the question at hand, leaving the matter of detail to direct reference to the books.
The Beginnings of Ifta:
The point on which all the above-mentioned books and historical accounts concur is that after the demise of the Prophet, may peace and God's blessings be upon him and his Household, other Muslims referred to the learned among the Companions and reciters of the Qur'an among them for guidance on the issues of the Shari'ah and acted in accordance with their fatwas, whose basis was either what they had heard from the Prophet, may peace and God's blessings be upon him and his Household, or their own ijtihad, in cases where they had heard nothing from him on an issue. Rather, it has been mentioned in some historical accounts-and al-Maqrizi seems certain about it-that ten among the Companions known as "al-`Asharah al-Mubashsharah" used to practise ijtihad and give fatwas during the lifetime of the Prophet, may peace and God's blessings be upon him and his Household; but as we said earlier this remark is problematic.
However, there is no doubt that the Companions became authority on religious issues after the demise of the Prophet, may peace and God's blessings be upon him and his Household. They went to different Islamic lands where they settled, teaching the Qur'an and the ahkam.
After the death of the Prophet, may peace and God's blessings be upon him and his Household, the Companions dispersed in different lands and only some of them remained with Abu Bakr at Madinah. Abu Bakr used to adjudicate on the basis of what he knew of the Qur'an and the Sunnah, and when he had nothing to lean upon he would refer to the Companions who were present. When the Companions too knew nothing in that regard, he resorted to ijtihad for ascertaining the hukm. 
Similarly, every Companion who arrived in a particular town used to practise ijtihad in matters concerning which he did not find anything in the Qur'an and the Sunnah.
Al-Maqrizi observes that when Abu Bakr died and other territories were conquered during the period of 'Umar and after him, the dispersion of the Companions increased further and the governor of each province would practise ijtihad even if no Companion were present.
This remark is explicit that the governors of provinces were considered an authority even if they were not Companions (Ashab).
The Cause of Divergent Fatwas:
The reasons behind divergent fatwas of the Ashab are given at length by al-Maqrizi. Here is a
summary of what he has to say:
Certainly every Companion did not have the opportunity to be in constant company of the Prophet (s) to record his pronouncements with a bearing on the ahkam. Rather, during his lifetime only some of the Companions were present at a time. Thus when some of them heard the Prophet's answer to any question, others missed the opportunity. When the ashab scattered far and wide after his (s) demise, so also did the ahkam narrated by them from him (s). Thus only a part of these ahkam were narrated in any town, so that the ahkam that were accessible to someone living in Madinah differed from those accessible to someone residing in Egypt. Likewise, that which an Egyptian knew was not known to the Syrian; what the Syrian had received was not accessible to the resident of Basrah; that which was accessible to the Basran was unknown to the Kufan, and so on. The result was that each of them resorted to ijtihad on issues regarding which traditions were not available to them.
Further, due to the absence of uniformity in knowledgeability, grasp, and other powers and faculties, these mujtahids naturally differed in their ijtihad and opinions. Therefore, mere individual differences among the sahabah resulted in differences of fattva, and later this difference grew after the period of the sahabah. 
Al-Maqrizi adds: "After the Sahabah, the Tabi'un followed the fatwas of the sahabah mostly without opposing them." 
His qualification 'mostly' clearly implies that the Tabi'un also sometimes practised ijtihad despite the presence of a Sahabi's opinion, and likewise the Tab' al-Tabi'in who followed the Tabi'an in this regard.
Mawlawi Shah Wali Allah, in 'Iqd al-jid fi ahkam al-ijtihad wa al-taqlid, says:
The Ummah concurs regarding reliance upon the salaf (earlier generations) for the knowledge of the Shari'ah. Thus the Tabi'un relied upon the sahabah, the Tab' al Tabi'in upon the Tabi'un, and so on and so forth. Therefore, referring to the salaf, apart from being a matter of consensus, is also considered praiseworthy by reason (aql). 
I say: He means the praiseworthiness of someone ignorant about something referring to another who knows it.
To sum up that which has been said hitherto, during and after the era of the [early] caliphs, the Muslims, in matters pertaining to ahkam al-din, referred to scholars and reciters of the Qur'an from among the Companions who had settled in various towns, and the Companions issued fatwas either on the basis of what they had heard from the Prophet, may peace and God's blessings be upon him and his Household, or the opinions they formed through ijtihad. After the Companions they followed the differing fatwas of the Tabi'un or those who were appointed as governors in the provinces. These differing fatwas first circulated in their respective provinces and later spread gradually to other parts of the Islamic world in accordance with the exigencies of the time and favourable chance. This was the practice of the Muslims for several years.
Mawlawi Shah Wali Allah, in his treatise al-Insaf, observes:
During the first and second centuries the people did not concur on the taqlid of one particular madhhab (school of law); rather, they followed the ahkam received from their ancestors or the local `ulama' who had acquired the ability to deduce the ahkam, completely or partially, from the Qur'an and the Sunnah ... 
From what he has observed it is obvious that for two centuries after the advent of Islam millions of Muslims lived and died professing Islam without knowing even the name of any of the legal schools that emerged in the second and third centuries, during which their founders were born, leave alone their following or identifying themselves with any of them.
Clearly it is neither a part of the Islamic creed nor among its prerequisites to follow a particular school of law founded by a specific person or to opt for one of the four schools of law.
About the post-Sahabah and the post-Tabi'un period, nearly two centuries later, al-Maqrizi observes:
After the period of the sahabah and the Tabi'un, the matter rested with the fuqaha' of various cities, i.e. Abu Hanifah, Sufyan and Ibn Abi Layla at Kufah, Ibn Jurayj in Makkah, Malik and Ibn al-Majishun at Madinah, 'Uthman al-Taymi  and Siwar in Basrah, al-Awza'i in Syria, and al-Layth ibn Sa'd in Egypt. These fuqaha' either referred to the Tabi'un or Tab' al-Tabi'in or practised ijtihad. 
The influence of most of these fuqaha' in the above-mentioned cities grew gradually until they became the imams of their legal schools by which their followers came to be identified. However, before their popularity the schools had no name and no Muslim ever identified himself with them at that time.
From what we have said it becomes clear that the schools of law emerged after the era of ,the Tabi'un and after their imams and gradual spread of their influence and fame. This happened at the end of the second century and the schools of law kept multiplying gradually till the beginning of the fourth century, or even during it, and were not limited to the four schools.
The Surviving Legal Schools:
Ahmad Taymur Basha, in his aforementioned article, states:
The madhahib were many and among them are the four schools which arc followed by the majority of Muslims to this day. They are:
-the Hanafi school, attributed to Imam Abu Hanifah Nu'man ibn Thabit al-Kufi (80-150/699-767).
-the Maliki school, attributed to Imam Malik ibn Anas (93 -179/711-795).
-the Shafi'i school, attributed to Imam Muhammad ibn Idris al-Shafi'i (150-204/767-819).
-the Hanbali school, attributed to Imam Ahmad ibn Hanbal (164-241/780-855).
These four schools have survived to the present day.
The Extinct Schools:
The madhahib which have been abandoned are:
-The madhhab of Sufyan ibn Said al-Thawri (97-161/715-777).
-The madhhab of al-Hasan ibn Yasar al-Basri (21-110/641-728).
-The madhhab of 'Abd al-Rahman ibn 'Amr al-Awza'i (88-157/706-773).
-The madhhab of Ibn Thawr, Ibrahim ibn Khalid al-Kalbi (d. 246,/-860).
-The madhhab of Dawud ibn'Ali al-Isfahani al-Zahiri (201-270/816-883).
-The madhhab of Muhammad ibn Jarir al-Tabari (224-310/ 838-922). This madhhab was promoted by Abu Bakr ibn Abi al-Thalj (d. 325/936), and after him by his student al-Qadi al-Mu'afa ibn Zakariyya al-Nahrawani (d. 390/999).
Among imams of the madhahib are also to be counted "the fuqaha' of the towns," mentioned by al-Maqrizi, who used either to refer to the Tabi'un or the Tab' al-Tabi'in or practised ijtihad. Among them are:
-Abu al-Harith, Layth ibn Sa'd ibn 'Abd al-Rahman al-Fahmi al-Khurasani (b. 94/712 d. 175/791 in Cairo), he was the imam of the people of Egypt both in hadith and fiqh.
-Ibn Jurayj, 'Abd at-Malik ibn 'Abd al-'Aziz (80-150/699-767), he was the imam of the people of the Hijaz during his period.
-Al-Majishun, 'Abd al-'Aziz ibn 'Abd Allah ibn Abi Salamah al-Madani al-Isfahani, faqih, hafiz and thiqah (trustworthy). Died in Baghdad in 164/780.
-'Uthman ibn `Umar ibn Musa al-Taymi  (d. circa 145/762). He was a judge during the reign of al-Mansur.
Apart from these there were other madhahib pupular in different regions whose imams, in their lifetime and later, had been authorities consulted and referred to for fatwas and ahkam, with groups of followers, big or small, among Muslims. Their fatwas were acted upon for a period of time, long or short, until they were abandoned, becoming obsolete with the passing away of their followers.
As to the madhahib which did not last for long, followed as they were by a group of Muslims only during the lifetime of their imams, there were countless. These became extinct with the death of their followers.
The aforementioned imams, apart from the differences of fatwa and opinion, also differed in respect of prestige and degrees of eminence, in their renown, and the extent of popularity or lack of it in different regions.
All this was the result of the presence of certain advantageous factors as well as those of chance in favour of some of them to the exclusion of others, or because times and circumstances were favourable to a imam and unfavourable to others.
[Factors Responsible for the Relative Influence of Some Madhahib:]
Among the factors that were effectual in giving precedence to a particular school was the number of scholars associated with it, students, patrons, promoters, supporters, and zealots, and the degree of their prestige, influence and power in propagating it.
Similarly the absence of the above factors resulted in lack of prestige, advancement, and propagation, leading to the decline of the popularity of the founder, gradual neglect, and ultimate extinction. This process continued till the madhhab became totally extinct and forgotten as if it were not a thing worthy of mention.
The unfavourable factors were responsible for the extinction of most of the legal schools that emerged about the end of the second century or later, while the favourable ones led to the advancement, propagation, and survival of the four schools that we find today.
The historical accounts guide us to the impact. of these factors in their continued survival, that it was due to the power of their followers and students and the authority exercised by princes, caliphs and others. It would not be inappropriate to mention some of them.
In the fourth volume of his al-Khutat, al-Maqrizi mentions what can be summarized as follows: Al-Qadi Abu Yusuf was appointed judge by Harun al-Rashid and later, after 170/786, he came to occupy the post of chief justice (qadi al-quddat). He did not appoint anyone to a judicial post except someone of his own choice, and since he was one of the closest disciples of Abu Hanifah, he selected for the provincial judicial posts of of Khurasan Iraq Syria, and other places only those who were followers (muqallidun) of Abu Hanifah. Thus it was he who was instrumental in propagating the madhhab of Abu Hanifah in different regions.
In the early stages of propagation of the Hanafi madhhab in the east, the Maliki school spread in west Africa through Ziyad ibn `Abd al Rahman, the first one to introduce the Maliki school in that region. The first to introduce the madhhab of Malik in Egypt in 163/779 was `Abd alRahman ibn al-Qasim.
Al-Maqrizi says that the madhhab of Muhammad ibn Idris al-Shafi'i spread in Egypt following his arrival in Egypt in the year 198/813. He further adds:
The madhhab practiced in Egypt was either that of Malik or al-Shafi'i until the invasion of Egypt by Jawhar at the command of the troops of his master, al-Mu'izz li-Din Allah Abu Tamim Ma'add, the Fatimid caliph, in 358/968. Thenceforth the Shi`i school gained currency to such an extent that apart from the Shi'i madhhab there remained none other in Egypt. 
This shows that the madhhab of Abu Hanifah either did not enter Egypt or was not made the official legal school in Egypt and its surrounding regions, a vast area, until about the 7th/13th century, whereas it was the first madhhab to be introduced in the eastern parts. This happened due to the influence of certain historical factors and exigencies which existed in some parts and not others. Similarly, the Hanbali school became popular in the areas surrounding Egypt nearly the same time as the Hanafi school.
In Shadharat al-dhahab, in the biographical account of Shams al-Din Muhammad ibn `Abd al-Wahhab at-Harrani at-Hanbali (d. 675/1276) it is stated that he assumed the post of qadi in some parts of Egypt and was the first Hanbali judge in that country. 
This is also clear from what al-Maqrizi says following his above mentioned remarks: "Then, during the reign of Baybars al-Bunduqdari, four judges were appointed in Egypt: a Shafi'i, a Maliki, a Hanafi and a Hanbali." 
Beginnings of Restriction of the Madhahib
From the appointment of a separate qadi for each madhhab during the reign of al-Bunduqdari, who came to power on 17th Dhu at-Qa'dah 658/1259 and died in 676/1277, it appears that official status was accorded for the first time to all the four madhahib in Egypt during this period. Before him, the Hanafi and Hanbali schools were not officially recognized in this manner. Al-Maqrizi observes in this context.
This, i.e. the assumption of the office of judgeship by four-continued from 665/1266 until the time when there remained no other madhhab except these four in all Islamic towns that was counted among the madhahib of Islam. Anyone who followed any other madhhab was regarded with hostility, disowned and barred from judicial posts. The testimony of a person was not accepted unless he was a muqallid of one of these four schools. Throughout this period the fuqaha' of these madhahib issued decrees in these towns ruling that it was obligatory to follow these madhahib and unlawful to adhere to any other madhhab. This practice continues to this day. 
Our citation from al-Maqrizi's observations ends here, and from it the following conclusions may be drawn:
1. As pointed out earlier, the impact of the causes and factors in the propagation of the four madhahib was decisive, considering that these madhahib had totally disappeared from Egypt after 358/968 for years on during the era of the Fatimid caliphs. But later they were revived after their disappearance in 567/1171 and were then jointly accorded official recognition in 665/11266 which state continued until 804/1401 when alKhutat was compiled.
The causes affecting the course and continuity of the four madhahib were stronger, and hence their growth and advancement. The other schools retreated till they became gradually extinct after 665/1266.
2. Around the year 665 some unsightly and scandalous things were associated with Islam and enormities were committed in the name of religion. This was despite the fact that the Lawgiver had based the laws of Islam on harmony and accord amongst Muslims. He had instituted congregations and gatherings to promote the spirit of unity calling the people to mutual love and friendship, ordering them to cooperate with one another in every positive matter and binding Muslims together with the firmest bond ('urwat al-wuthqa) of brotherhood so that they would not disperse and remain united against others.
It is regrettable that at this time mutual hostility amongst Muslims was made a part of religion. Consequently the patrons of the four madhahib started to show hostility towards the followers of other schools, who like them pronounced the shahadatayn, prayed facing the Holy Ka'bah, performed Hajj, sought spiritual purification, and performed all obligatory and supererogatory acts which had reached them from the Prophet of Islam through authentic chains of transmission.
Someone might remark that this is not the first crisis in Islamic history. One might recall that which the pages of history disclose-specially those like the Kamil of Ibn al-Athir-concerning the battles and disturbances which took place in the preceding centuries amongst the Muslims, especially the conflicts that occurred in Baghdad and other cities between the followers of the four madhahib themselves (some of which we shall mention shortly) and between them and other Muslims.
I would say in answering that the difference between this event and what took place earlier is as great as the distance between the heaven and earth, because the cause of the preceding conflicts was nothing except ignorant fanaticism which aroused the common people and incited ignorant elements to commit repulsive deeds. The ruling authorities, if asked, would strongly disavow them and tried, albeit outwardly, to absolve themselves by laying its blame on the neck of the ignorant.
But this time the authorities proclaimed that following any madhab other than these four by a Muslim was a major sin and atrocity from which lie had to be restrained by everyone who had the power. In effect, it was an act that expelled one from the fold of Islam: his testimony was not to be accepted and if he were a judge he had to be dismissed from his post. Were it not considered an act of apostasy, mere commission of a major sin does not disqualify one, in their opinion, from holding the post of a judge or giving witness.
This announcement by the leaders of the Ahl al-Sunnah was certainly a blow to Islam, causing as it did animosity and hatred amongst Muslims, shattering their unity, dividing them against one another and causing total dispersion.
3. Around the year-665/1266 the fuqaha' decreed that it was obligatory to follow one of the four madhahib and unlawful to adhere to any other. This too was one of the greatest calamities which befell Islam, considering that nearly seven centuries had passed since the advent of Islam during which countless number of people had died professing the Islamic creed and during the first two centuries not a single person had ever heard the name of any of these madhahib. Even after the first two centuries, the Muslims enjoyed complete freedom with respect to religious law, with laymen following a mujtahid whom they relied upon and the mujtahids deducing the ahkam from the Qur'an and the Sunnah on the basis of jurisprudential principles upheld by them for acting on the Prophetic Sunnah. So what was it that had obliged the generality of Muslims this time, both the muqallid layman and the mujtahid legist, to limit themselves to the taqlid of the four imams in matters of laws of the Shari'ah?
In view of what was mentioned earlier concerning these madhahib, their beginnings, the mode of their propagation, their gradual development, and the role of certain factors which led to their prevalence over other schools through the domination and coercive power of governments, on what grounds of the Shari'ah was it obligatory to follow one of the four madhahib and intrinsically unlawful to follow any other? This has been clearly spelled out by the distinguished Iraqi historian, Ibn al-Fuwati, on page 216 of al-Hawadith al-jami'ah, while discussing the events of 645/1247, i.e. eleven years before the downfall of the 'Abbasids during the reign of al-Musta'sim who was executed by Hulagu in 656/1258.
The Beginnings of Restriction on the
Madhahib in Baghdad:
Before recounting the events of 645/1247, Ibn Al-Fuwati, in the account of 631/1233, mentions how the college of al-Mustansiriyyah was inaugurated in Baghdad during the month of Jamadi al-Thani of this year. He observes:
Its construction was started on the orders of al-Mustansir billah in the year 625/1227 under the supervision of the Ustadh al-Dar Mu'ayyid al-Din Abu Talib Muhammad Ibn al-Alqami. It was divided into four quarters on the day of its inauguration. The front right-hand side quarter was given to the Shafi'is, the quarter to the left to the Hanafis, the interior right-hand side quarter to the Hanbalis and the one to the left to the Malikis. Sixty-two fuqaha'-that is, students of fiqh and ahkam-were chosen for each madhhab. Thus the total strength of the students in the school was 248. There were two teachers, a Shafi'i and a Hanafi, and two assistant-teachers, a Hanbali and a Maliki. Each one of them was given a monthly salary, stipend and daily food ration, cooked and uncooked. Also several qurra' (reciters of the Qur'an) were appointed to teach qira'ah, some [traditionists] to teach hadith, and some [physicians] to teach medicine. The school was under the supervision of al-Qadi Abu al-Najib'Abd al-Rahman [who was also responsible for] the changing and replacement of persons, internal and from outside, till 645/1247. In this year, the four teachers who were charged with the teaching of fiqh of the four madhahib were summoned and ordered not to mention their own works to their students of fiqh and not to compel them to memorize anything from those writings; rather, they were to confine themselves to the opinions of the early masters (masha'ikh) with due reverence, seeking blessing (barakah) through them.
To this, the response of Jamal al-Din Abu al-Faraj 'Abd al-Rahman ibn Muhy al-Din Yusuf ibn al-Jawzi was total compliance. He was initially a muhtasib (inspector of weights and measures) in Baghdad and later occupied the position of his father, Muhy al-Din Yusuf ibn al-Jawzi, as the teacher of Hanbali fiqh in the said madrasah. He is different from Abu al-Faraj 'Abd al-Rahman ibn 'Ali ibn Muhammad ibn al-Jawzi, the wa'iz, who died in 597/1200 and belongs to a later period. Then the teacher of Maliki fiqh, Siraj al-Din 'Abd Allah al-Shirmahi  sent in his response and acceptance. But Shihab al-Din al-Zanjani, the teacher of Shafi'i fiqh and the most competent of judges, 'Abd al-Rahman al-Lamghani, the teacher of Hanafi fiqh, rejected the proposal stating that 'the masha'ikh were men, and so are we,' or something to that effect, implying that they were on a par with the early masha'ikh. The teachers were summoned to the house of the vizier Mu'ayyid al-Din Muhammad Ibn al-Alqami, who had supervised the construction of the madrasah as its builder, and he informed the caliph, al-Musta'sim, about the situation. The caliph then ordered that the teachers were to commit themselves to mentioning [only] the statements of the masha'ikh and to honour them, whence all of them submitted their compliance.
Here ends the summary of Ibn al-Fuwati's account to which I have added my own explanations.
Ibn al-Fuwati's account confirms al-Maqrizi's statements, except that the latter's discussion was limited to Egypt. Hence, he mentions the official recognition granted to the four madhahib in Egypt and the decree which at one stroke made it obligatory to follow these madhahib and no other. This occurred during the reign of al-Bunduqdari when the four qadis were appointed in 665/1266. Before this they had no such kind of official recognition. However, Ibn al-Fuwati mentions the official recognition of the four madhahib in Baghdad, the seat of the caliphate and the centre of Islamdom, which took place in 631/1233, when the al-Mustansiriyyah college was inaugurated and divided into four wings assigned to the followers of the four madhahib. Though earlier no such restriction existed, in 645/1247 the teachers of the madrasah were ordered not to transcend the opinions of the early mashd'ikh, whose sanctity was to remain secure and the blessing of their precedence in learning and religion to be invoked.
Ibn al-Fuwati mentions the excuse which the fuqaha' submitted in declining to comply with the imposition to confine to one of the four madhahib and the proscription on others, making it clear that it was done on the order of the caliph and that they were coerced to accept it, as is made clear by [the initial resistance of] the Shafi'i and the Hanafi teachers. Al-Maqrizi, however, was not in Baghdad and was not aware of the caliph's imposition.
Hence he does not mention it and ascribes the order to the fuqaha'. And if this excuse were not considered acceptable by the fuqaha', they would be deemed to have committed a mistake-as will be explained later-in limiting the madhahib to the four.
As to the caliphs, the basis of their directives was nothing except the exigencies of mundane politics, although they apparently based their decrees on the consent of the f uqaha' who assisted them in their objectives. For example, Ibn al-Salah 'Uthman ibn 'Abd al-Rahman ibn 'Uthman al-Shahruzi, the commentator of al-Wasit, a work on Shafi'i fiqh,
who was appointed a teacher at Dar al-Hadith by al-Malik al-Ashraf and died there in 643/1245, issued a fatwa that it was unlawful to follow any except the four Imams, citing as his basis the consensus of scholars, as mentioned by Muhammad Mustafa at-Maraghi, the shaykh of al-Azhar, on page 17 of al-Bahth fi al-tashri' al-Islami  ...al-ziwaj wa al-talaq. 
Factors Responsible for Restricting the
Number of Madhahib:
The reason behind the limitation on the number of madhahib, mentioned by Ibn al-Fuwati and as disclosed by historical accounts, is one of these two:
First: The first of these is the one stated in the Riyad al-'ulama' in the biographical account of al-Sharif al-Murtada 'Alam al-Huda. After mentioning the Tahdhib al-ansab wa nihayat al-a'qab by the genealogist al-Sayyid Abu al-Hasan Muhammad ibn Muhammad ibn 'Ali ibn al-Hasan al-Husayni al-Musawi, the author observes: It is widely known among the 'ulama' that the Ahl al-Sunnah, during the reign of the caliphs, when they encountered such dispersion of madhahib on legal issues (furu' al-din) and divergence of opinions and tendencies that it was impossible to keep track of them-considering that each of the Sahabah, Tabi'un, and those who came after them, up to the period of these caliphs, had his own madhhab and personal views in regard to the issues of the Shari'ah and its practical laws-resorted to curtailing the madhahib and were compelled to dissolve most of them. Therefore, they concurred upon accepting some of them. 
Hence they selected the four madhahib due to the large number of their followers and their abundant wealth.
Second: The extensive and endless differences in opinions and views resulting from the practice of ijtihad forced the caliphs to reduce their number, and as they were incapable of setting aside some of these four madhahib in view of the extent of conflict it entailed and given the zealotry of their followers, they resorted to limiting the madhahib to the four.
The evidence of their inability to set aside any of the four madhahib is provided by al-Maqrizi in al-Khutat where he reports that when Abu Hamid al-Isfara'ini wrote to Sultan Mahmud ibn Subuktigin in 393/1002 that the caliph had transferred the control of the judiciary from the Hanafis to the Shafi'is, this led to such a great confrontation between the followers of the two schools that the caliph was forced to change his mind. He was indignant at Abu Hamid, but had to reinstate the Hanafis to their earlier position. 
Anyone intending to learn more about the intense bigotry of the followers of these four madhahib may refer to the chronicles pertaining to most of the years in Ibn al-Athir's al-Kamil. 
The author of Mu'jam al-buldan observes in the first volume, under the entry pertaining to Isfahan, page 373:
Destruction spread in Isfahan at this time and before it as a result of the prevalence of bigotry amongst the Shafi'is and the Hanafts and the unremitting wars between these two parties. Whenever one party gained ascendency, it plundered the quarters of the other and burnt them down and destroyed them, and no bond or treaty would restrain them. 
These civil disturbances, strifes, and bigotries were instrumental in shaping the policy of the caliphs in compelling the fuqaha' to restrict themselves to the opinions of the masha'ikh `as a mark of respect for them and for the sake of seeking blessing through them: The fuqaha' on their part accepted the caliphs' orders restricting the madhahib to four and invented reasons to justify it.
Of these reasons, as will be discussed shortly, is the [dogma of the] closure of the door of ijtihad after the period of the early masha'ikh. This step of theirs was in accordance with the adage
(`The people follow the creed of their kings'). Al-Ghazali, as quoted by Mawlawi Shah Wali Allah in his book al-Insaf, has expressed this very well in the following words:
After the period of Rashidun Caliphs, the caliphate was undeservedly taken over by a group of people who had no knowledge of the ahkam. Therefore, they needed the collaboration of the fuqaha'. Some of them of the top rank fled when accosted for service, while others sought the nearness of the caliphs and wrote books on theology, polemics, and differences between the madhdhib, each according to favourable circumstances and available means. 
Among such fuqaha' we have mentioned Ibn al-Salah (d. 643/1245) earlier.
One can conclude from the statements of reliable historians mentioned here, i.e. Ibn al-Fuwati in al-Hawadith and al-Maqrizi in al-Khutat, that the restriction of the following to the four madhahib and the proscribing of adherence to any other madhhab took place during the middle of the 7th/13th century and without any religious basis to justify it. Rather, it came about as a result of the policy of some caliphs and was complied with by those who were affiliated with the rulers and caliphs or sought nearness to them, and those who strived to obtain the posts of judges, imams, scribes, secretaries, etc.
The Mujtahids After the Limiting of the
The most eminent among major scholars, free men seeking to deliver themselves from the servility of taqlid, have shown their independence throughout history and founded their own madhahib and issued their own fatwas, such as Imam Jar Allah Mahmud ibn `Umar al-Zamakhshari (d. 538/1143) and Imam Muhy al-Din Muhammad ibn `Ali ibn al-`Arabi (d. 638/1240), although they have been associated with one of the madhahib as per the demands of their respective times. Similarly Ahmad ibn Taymiyyah al-Hanbali (d. 728/1327) professed to be a Shafi`i, and so did many of his followers; but his fatwas, which are followed by the Wahhabis, do not accord with the views of any of the four madhahib and indicate his independent approach. Al-Dhahabi says about him: "He deserves to do ijtihad because all its requisites are present in him."
Similarly, many eminent scholars who have lived throughout these centuries down to our own times did not submit to the restriction on the madhahib and did not believe that any Islamic precept made it obligatory upon all Muslims to follow one of the four Imams or made it unlawful for them to go beyond their rulings in matters of ahkam, which cannot be known except through inference from the Qur'an and the Sunnah. That is because none of the sources of Islamic law, i.e. the Qur'an, the Sunnah, consensus (ijma') and reason ('aql), proves this restriction.
Adherence to any madhhab was not known to the Muslims from the time of advent of Islam up to the period when the four madhahib gained currency, and this was nearly after two centuries. But even then, though the concept of madhhab had developed among them, the restriction making it obligatory to follow one of the four madhahib and proscribing others, as mentioned earlier, took place in the 7th/13th century at the caliph's orders for political reasons. Otherwise, the ability to deduce the ahkam from the Qur'an and the Sunnah is neither confined to any particular country, nor limited to particular persons to the exclusion of others.
Abu al-Tayyib Siddiq Hasan Khan, in Husal al-ma'mul min 'ilm al-usul, p. 186, while rejecting the limitation on madhaab to the four and calling for the revival of ijtihad, observes:
One who limits the grace of God to some of His creatures and confines the ability to understand the sacred Shari'ah to those of the past eras, is guilty of insolence towards God Almighty and His Shari'ah, which has been laid down for all His servants who adhere to the Qur'an and the Sunnah. If adherence to the Holy Quran and the Sunnah is limited to the people of the bygone ages and if there remains nothing for those who came after them to do except imitate their predecessors, and if they cannot deduce the knowledge of God's laws from the Qur'an and the Messenger's sunnah, what are the grounds of this false distinction and this spurious dogma? Is naskh (abrogation) anything other than this? Glory be to God, this is a great calumny! 
Muhammad Farid Wajdi, a contemporary writer, in the third volume of the Da'irat al-ma'arif, at the beginning of his discussion on ijtihad, under the root j-h-d, says:
When the Muslims were afflicted by the malaise of social stagnation and affected by the inability to understand the secrets of the Shari'ah, they took resort in the excuse of the closure of the gates of ijtihad and legal inference to conceal their own weakness. The truth is that this door remains open, as affirmed by express statements of the Qur'an and the Sunnah, till the Day of Resurrection. 
Then, in nearly sixty pages, he presents his research about ijtihad, the details of its various phases, its history, and its perpetual necessity.
In short, to consider ijtihad as permissible for the early generations and unlawful for the later generations is a form of baseless discrimination, acceptable to none except those whom Abu al-Tayyib al Siddiq Hasan Khan calls `captives of taqlid'. He says: "The captives of taqlid are not like those to whom God has opened the doors of the higher teachings (ma'arif) and given them a knowledge with which they free themselves from the imitation of men." 
There are other scholars of repute among later as well as the contemporary generations, among them Shaykh Muhammad `Abduh and his pupil, the author of al-Manar, as well as other outstanding and independent contemporary thinkers who have freed themselves from the yoke of taqlid and declared their opposition to those who consider the door of ijtihad as closed.
Partisans of Restriction on Ijtihad:
Among the partisans of the restriction who advanced arguments in its favour is Mawlawi Shah Wali Allah Ahmad ibn `Abd al-Rahim al Dehlawi in his two aforementioned books. Unfortunately his arguments beg the question. His research in both the books contains nothing except claims unbacked by evidence from revelation or reason. The essence of his research is a chronological classification of the generations of Muslims from the time of demise of the Prophet, may peace and God's benedictions be upon him and his Household, to his own time into three categories and an assignment of certain duties to each.
The First Category:
This consisted of Muslims who lived during the first and the second centuries. To the laity ignorant of the rules of the Shari'ah among them he assigns the duty of referring, in every issue, to some scholar of the religion, whosoever that may be, who had acquired the ability to deduce these rules, and it was not obligatory upon them to imitate any one particular individual. He observes: "During the first and the second centuries the people were not united in following a specific madhhab. The common people learnt the ahkam from their parents or the `ulama' of their city who possessed the ability, complete or partial, to infer the ahkam from the sources of the Shari'ah." 
The Second Category:
To it belong the generations which lived from after the second up to the beginning of the fourth century. He classifies the people of this category into three classes. The first of these were the full-fledged independent mujtahids, who had authority over three things: first, the freedom to apply the principles of jurisprudence and legal rules; second, to reconcile [conflicting] traditions; and third, to infer detailed rules. 
One who did not have command over all these three was obliged to imitate an independent, mujtahid, irrespective of whether he was an ignorant layman doing taqlid or one belonging to the third class, that of `affiliated mujtahids' (al-mujtahid al-muntasib), that is, one who bases his fatwa on the opinions of one of the independent mujtahids constituting the first class and does not go beyond their opinions. He remarks:
After the first two centuries it was obligatory upon every muqallid and affiliated mujtahid to follow the madhhab of some specific independent mujtahid. 
The Third Category: To it belong the Muslims who lived during the period extending from the beginning of the 4th/10th century to the author's own time. He divides them into two kinds,
ignorant laymen and affiliated mujtahids, and says:
It is obligatory upon a layman to imitate an affiliated mujtahid and no other because of the impossibility of there being an independent mujtahid from that time to this day.
He says this after dividing the mujtahids into two classes, the independent and the affiliated, and his claim is that the independent mujtahids became extinct from the beginning of the 4th/10th century and it is not possible for one to exist in view of the non-realization of the above-mentioned qualifications. Hence that which can possibly remain is the second class, that of affliated mujtahids, and it is obligatory for the laity to do their taqlid.
Summarily, it was obligatory for those in the first category to refer to any scholar; for those who belong to the second category to refer only to an independent mu4tahid; and for those belonging to the third category to refer to the affiliated mujtahid, because there exists no other. Then he anticipates a possible objection against this view and goes on to refute it in this manner:
If you say: How is it that after two hundred years it became obligatory to follow a particular madhhab while it was not so earlier?
I will reply: That which is actually obligatory is that there be in the Ummah someone who knows all the ahkam for the sake of their observance, and the prerequisite of an obligation is also obligatory. Therefore, if there exist numerous ways of meeting an obligation, anyone of them may be chosen, but if all ways except one are closed that one becomes specifically binding. 
The Gist of Shah Wall Allah's
In my view the gist of his elaborate discussion consists of two claims:
The First Claim:
During the first two centuries it sufficed to refer to any mujtahid, but after this period when there existed the imams of the madhdahib who were independent mujtahids, it became obligatory to refer to anyone among them specifically. When one asks the reason for this distinction and the cause for something becoming obligatory which was not so earlier, he gives a reply, as already quoted under the title . . . , which is not satisfactory, unless he implies by it what we shall mention shortly along with its reply.
The Second Claim:
This concerns the closure of the door of ijtihad from the beginning of the 4th/10th century, making it obligatory upon all Muslims up to the present to refer to affiliated mujtahids. Here he is content to claim that the conditions for independent ijihad ceased to exist from that time onwards. But this amounts to begging the question, especially as this claim disregards figures of major eminence who lived during this period and whose scholarly books and writings testify to their having attained the highest levels of ijtihad.
In any case, he does not mention in his book al-Insaf the official decree restricting the madhahib to four and making it binding to refer specifically to them to the exclusion of others. Although he raises the issue of the restriction in his book 'Iqd al-jid fi ahkam al-ijtihad wa al-taqlid, but there also he does not explicitly mention that it is obligatory to follow the four madhahib. In fact, he appears to imply the preferability of referring to them, for under the chapter entitled "Bab ta'kid al-akhdh bi al-madhahib al-arba'ah wa tark al-khuruj `anha"  (`Chapter Concerning
Emphasis on Referring to the Four madhahib and not Going Beyond Them') he observes:
You should know that there lies a great benefit in adhering to these four madhahib and a great harm in disregarding all of them. We will explain this by giving a number of reasons.
Then he goes on to give reasons which do not substantiate his claim. I shall mention some of them here along with their inadequacies. These are as follows:
1. With the passage of time and betrayal of trusts, it was no longer permissible to rely upon the views of the evil `ulama, unjust judges, and the muftis who issued fatwas for profane ends (ahwa').
I say: But there is no obstacle to relying upon those `ulama', besides the four imams, who do not possess the above-mentioned characteristics, because the allegation that all others were evil except the four imams is something which no Muslim would have the temerity to claim.
2. When the other madhahib gradually became extinct, the majority of Muslims inclined towards these four madhahib, and the Prophet, may peace and God's benedictions be upon him and his Household, has said (`Follow the majority').
I say: How could the Prophet, may peace and God's benedictions be upon him and his Household, have said such a thing, and how is it conceivable that he would make it obligatory to follow those who are considered sinful by the Book of Allah, which declares:
Surely most men are transgressors. (5:49)
And you will not find most of them thankful. (7:17)
There are a large number of such statements in the Qur'an and hadith.
Moreover, the better recognized version of this tradition is ,  wherein there is a command to go to big cities because they are centers of various kinds of learning and have other benefits lacked by villages.
3. Another reason-and this is the major one given by him-is that there is a consensus of the Ummah on relying upon earlier generations for the knowledge of the Shari`ah. Therefore, it is inevitable for us to rely on their authority and not to accept anything except that which has been narrated from them through authentic chains and compiled in famous books together with clarifications of their most probable meanings, particularization or limitation of statements of a general import, and reconciliation of conflicting texts.
These characteristics are not found in any except the four madhahib, and there is no other madhhab possessing these qualities except the Imamiyyah and the Zaydiyyah. But since they are heretical, it is not permissible to rely upon their opinions. Therefore, the choice is restricted to following one of the four madhahib.
A Defence of the Imami School:
I say: Probably what he means is that if there exist several ways of fulfilling an obligation, any one of them can be chosen, but if all the ways except one are closed, that one will be specifically binding. The conclusion which can be drawn from his observations is that he admits that the four Sunni madhahib along with the Imami and Zaydi madhhabs fulfil the above-mentioned criteria of acceptance and reliance, but since the last two are deviant on account of containing heretical views, the choice is restricted to the four madhahib only.
In view of this assertion it should be said that the allegation that the Imamiyyah madhhab contains heresies is a monstrous calumny and slander-may God protect us from it.
To be sure, Shah 'Abd al-'Aziz, son of Shah Wali Allah, had the audacity to propagate these calumnies in the ninth chapter of his book al Tuhfat al-Ithna 'Ashariyyah which deals with the issues of fiqh and Shari'ah. 'Allamah Dehlawi, in the ninth volume, of his book al-Nuzhat al Ithna'Ashariyyah, a refutation of the ninth chapter of the Tuhfah, refutes each one of his statements and proves the purity of the Imami school from any bid'ah and such laws as are not based on God's revelations to the Prophet, may peace and God's benedictions be upon him and his Household.
When it is established that the Imami madhhab contains no bid'ah, and as it stands on an equal footing with the four Sunni schools as per the admission of Shah Wali Allah, there remains no reason for preferring the four to the Imami madhhab; rather, the Imami madhhab enjoys priority over them because it has been transmitted through sahih and reliable chains of narrators from the Infallible Imams, who were divine 'ulama' who had inherited the knowledge from their ancestor, the Prophet, may peace and God's benedictions be upon him and his Household, and whom God, the Exalted, had imparted all the divine sciences which He had entrusted to His prophet (s). Hence they do not say anything except that which was revealed to their ancestor, who did not speak out of caprice ( [53:3]) and as we mentioned earlier, their chain of transmission goes back to the gateway of the Prophet's knowledge. 
All praise is for God who guided us to this, and we would not have been guided had not God guided us (7:43). What I have said is not out of any bias. By God, who has blessed me with being, I have not found in their statements and their writings and books (i.e. of the Ahl alSunnah), some of which I have mentioned here, and have not come across up to this day even a single piece of evidence supporting the claim that it is obligatory to follow one of the four madhahib and unlawful to adhere to any except these, nor any evidence for preferring these four madhahib to others. And God is witness over what I say, and all praise belongs to Him, at beginning and end.

. He is Muhammad ibn Ahmad ibn al-Junayd al-Katib al-Iskafi, an early Imami legist. Al-Najashi, in his Rijal, says about him: "Muhammad ibn Ahmad ibn al-Junayd, Abu 'Ali al-Katib al-Iskafi, notable amongst our companions, trustworthy and highly respected, a prolific writer."
He goes on to mention a large number of his works, and among them is a book containing a collection of 'masa'il' nearing two thousand in number, covering 2500 pages. Later he observes: "I have heard my trustworthy teachers say about him that he used to practice qiyas" (Rijal al-Najashi, [Qumm,1407b p. 385-388].
Al-Shaykh al-Tusi in al-Fihrist says about him: "Muhammad ibn Ahmad ibn al Junayd, kuniyah Abu 'Ali, was an excellent writer, but he used to practice qiyas. Therefore his books have been abandoned and are not referred to. He has written a large number of books" (p. 267). Then he goes on to mentions his books.
'Allamah Sayyid Mahdi Bahr al-Ulum (quddisa sirruh) observes: "Muhammad ibn Ahmad ibn al-Junayd, Abu 'Ali al-Iskafi, [was] one of the eminent and great figures of our sect and one of the earliest Imami scholars .... This shaykh, despite his eminence within the sect, his leadership, and great station, has been said to have employed qiyas, and this has been narrated about him by a group of major Shi'i scholars" (Sayyid Bahr al Ulum, Rijal, iii, 205-207).
Regardless of this, the scholars have not altogether disregarded his opinions because of his acting on qiyas, and this is clear from the following observation of 'Allamah Sayyid Bahr al 'Ulum: "It is known from what we have said that the correct view is to give credence to Ibn al-Junayd's opinions for determining issues of concurrence and disagreement, and this is the wont of major Imami scholars.
Concerning his having acted on qiyas and the like, that does not call for disregarding his books and not relying upon them, as observed by al-Shaykh al-Tusi-may God have mercy upon him-because the presence of difference among the fuqaha' regarding the basic principles of ahkam (i.e. jurisprudential principles on the basis of which the ahkam of the Shari'ah are deduced) does not necessitate non-reliance on their opinions on this basis, considering that from the earliest times to the present age, they have differed concerning the jurisprudential principles on which the detailed laws are based, such as their difference of opinion regarding khabar al-wahid and al-istishab (Sayyid Bahr al-Ulum, Rijal, iii, 221).
. The issue of the 'adalah (veritable authority) of the Sahabah, is one of the critical issues that have occupied an important place in discussions on the sciences of hadith and rijal (the study of the narrators from the viewpoint of their veracity). The majority of the Ahl al-Sunnah have inclined towards the view that all the Sahabah are 'adil (veracious authorities) and that it is not appropriate to apply to them the critical criteria of the science of-rijal (jarh and ta'dil) as applied to other Muslims.
Al-Ghazali, in al-Mustasfa, says: "The salaf (the early generations of Muslims) and the majority of the khalaf (those who came after the salaf) have accepted the 'adalah of the Sahabah on the basis that their 'adalah has been confirmed by God, the Almighty and the Glorious, and He has praised them in His scripture. We too hold the same belief about them, except where it is conclusively proved that one of them has committed a sinful act knowingly. And since this has not been proved, there is no need for ascertaining their 'adalah" (al-Mustasfa, p. 204).
There are among the Ahl al-Sunnah those who consider it valid to critically appraise their 'adalah, just as in the case of other Muslims, and that their Companionship of the Prophet (s) is of no consequence in this regard. But these scholars do not represent anyone except themselves in this belief. Apart from this, some Mu'tazilah have observed that the Companionship was effectual till the occurrence of strife, discord, and eventual bloodshed among them.
Whatever the case may be, most of the Ahl al-Sunnah unconditionally accept the 'adalah of the Sahabah and do not require a critical appraisal of their 'addlah.
Nevertheless, for anyone possessing a minimal knowledge of the history of the Prophet (s) and the Sahabah and the verses revealed about some of them, ascribing to them hypocrisy, opposition to the Prophet's (s) commands, and causing him (s) grievance, there remains no doubt that there were among the Sahabah those whose sinfulness is doubtless, especially when the Holy Qur'an itself dubbs one sahabi as fasiq where it declares:
O believers, if an ungodly man comes to you with a tiding, ascertain carefully, lest you harm a people in ignorance, and then repent for what you have done. (49:6)
It also explicitly states that there were liars among them:
Were it been an immediate gain and the journey easy, certainly they would have followed thee; but the distance was too long for them. Still they will swear by God, 'Had we been able, we would have gone out with you.' They cause their own selves to perish and God knows that they are truly liars.
God forgive thee, why didst thou give them leave until it was manifest unto thee those who spake the truth and thou hadst known the liars. (9:42-43)
It also observes about some of them:
Some of them there are that say, 'Exempt me and try me not;' surely into trial they have already fallen, and verily hell encompasses the unbelievers. I f good fortune befalls thee, it vexes them; but if thou art visited by any hardship, they say, 'Indeed we had taken care of our affair before,' and turn away rejoicing. (9:49-50)
It addresses some of them and says:
Say: 'Spend willingly, or unwillingly, it shall not be accepted from you; you are surely a transgressing people.' And naught prevents that their expendings should be accepted from them, but that they believe not in God and His Messenger, and perform not the prayer save lazily, and that they spend not but reluctantly. (9: 53-54)
These are some of the many verses revealed concerning some Sahabah and one rarely finds a surah in which God has not referred to them in some verse or verses. Therefore, is it justified to disregard these explicit Qur'anic verses and hold on to the concept of the 'adalah of all the Sahabah?
It is often said that such verses have been revealed concerning the hypocrites. But have the hypocrites been distinguished from the other Sahabah, isolated, and identified for all so that one is not misled concerning any of them? If not, then why should it be inappropriate to apply to them the criteria of ascertaining 'adalah (jarh and ta'dil)?
Fittingly does Mahmud Abu Riyyah observe in his book Adwa' 'ala al-sunnat al-Muhammadiyyah (5th edition), p. 350, wherein he says: "If the Companionship of those like Bishr ibn Marwan-on the assumption of its being factual-or that of al-Walid, were of any avail, it would imply that no act except apostasy is deterimental by the side of Companionship, as if Companionship were something greater than faith (iman). Such an opinion would be more extreme than the creed of Maqatil and his followers from among the Murji'ah. Moreover, what is to be done with such traditions as
('You do not know what mischief they caused after you'), which are mutawatir as to their meaning, and it may even be validly claimed that some of them are mutawatir in their wording. Those who claim to follow the Sunnah ascribe Companionship to someone or affirm it of him without any evidence, and then draw from it such conclusions as can be seen and base their religion on it. Has not God said,
(`if a transgressor comes to you with a riding, ascertain') about someone whose Companionship is certain and whose state has always been obvious despite his being a Companion? Further, among them were those who drank wine and committed other countless acts, which are not mentioned for the respect of the Prophet, may peace and God's benedictions be upon him, unless necessitated by some religious expediency.
And the greatest of expediencies is involved when something pertaining to religion is derived from a tradition narrated by Marwan, al-Walid, and others, which is the greatest betrayal of the religion of God and opposition to the explicit import of the noble verse. Any resentment of such an action does not imply the rejection of all the Companions, but rather an affirmation of their purity. So beware, do not be deceived!"

. The tradition
('My Companions are like the stars'), as expressly stated by several eminent scholars, is a forgery. Ibn al-Qayyim considers it da'if and a forgery (A'lam al-muqi'in, ii, 223).
Al-Ghazali, in al-Mustasfa, observes: "Some people claim that their position (i.e. of the Companions) is similar to that of others regarding the necessity of a scrutiny. Others say that their initial condition was 'adalah until the occurrence of civil war and hostilities, whence their state changed and there was bloodshed, and hence there is a need for scrutiny. Those who believe in the 'adalah of all the Sahabah base their claim on the saying of the Prophet 'My Companions are like the stars, whoever you follow you will be guided' and according to another version . . .
as ('whoever's statements you take... ). But this tradition is not sahih and is said to be fabricated"
`Allamah Sayyid Hamid Husayn al-Lakhnawi (1246-1306/1830-1888), an Indian scholar, as pointed out by the author himself in the text, has conducted extensive research on this tradition in his encyclopaedic work `Abaqat al-anwar f i imamat al A'immal al-Athar, which he wrote as a refutation of the chapter on Imamate of Shah `Abd al- Aziz al-Dehlawi's book al-Tuhfat al-Ithna 'Ashariyyah, in which he had disputed some traditions that prove the Imamate of Amir al-Muminin 'Ali, may peace be upon him. There he has established the tawatur of each one of the traditions in several large volumes.
