Salat al-Jamaat at means praying in congregation, with one person leading. The Person who leads is called the Imam, while those who follow him are called the Ma'mum or Ma'mumin (plural). As for the daily prayers, the minimum amount of people needed is two -one, Imam and one Ma'mum. For the Salat al-Jumu'ah (Friday) there must be a minimum of five people, including the Imam.

There is no Salat al-Jama'at for the Mustahab Salat with the exception of Salat al-Istisqa " or the invocation for rain; and for the Salat of 'Eid, which are offered on the day of 'Eid al-Fitr and 'Eid al-Qurban, which are mustahab during the time of occultation of the 12th Imam (may our souls be sacrificed for him).

The Salat is the most important act of worship in Islam, and if it is accepted by Allah (SWT), then all other acts of worship are accepted as well. However, if the Salat is not accepted, then all other actions also will not be accepted. It has been narrated from the 6th Imam, Ja 'far ibn Muhammad as-Sadiq, peace be upon him, quoting his forefathers up to the Messenger of Allah, peace be upon him and his family, that he said:

“If there was a strem at the house of any one of you in which he washes himself five times a day, will ther remain any dirt on your body? Verily, the likeness of the Salat is the same as the stream. The Person who establishes the ritual prayers clears out his sins thereby, execpt for the sin that take him out from the faith that he believes in”. (Bihar al-Anwar, Vol. 82, Pg. 236)

In Islam, perhaps there is no other Mustahab act that carries such benefits and results as Salat al-Jamaat. As for the importance of it, we quote one narration in which it has been mentioned that:

· If two people form a Jama'at, the reward for one Rak'at will be equal to one hundred and fifty prayers.
· If there are three people, the reward for one Rak'at will be equal to six hundred prayers.
· If there are four people, the reward for one Rak'at will be equal to one thousand two hundred prayers.
· If there are five people, the reward for one Rak'at will be equal to two thousand four hundred prayers, & such does the reward multiply, that if there are more than ten people in the Jama'at, then if all the skies were paper, all the seas were ink, all the trees were pens, and all the men, Jinn, and Angels got together as scribes to record the reward of one Rak'at, they would not be able to do it.

In the same narration, it is mentioned that the Takbir (Allahu Akbar) that the believers say after the leader of the ~alat is better and more beloved to Allah that sixty thousand Hajj and 'Umrah, and better than this world and all that is in it- sixty times over! Each Rak'at that the believer performs in Jama'at is better than offering one hundred thousand dinars in charity to the poor, and his sajdah is better than if he was to free one hundred slaves.

It has been emphatically recommended that all obligatory Salat, with special emphasis on Salat al-Fajr, Maghrib and 'Isha be offered in congregation. More stress has been laid upon those who live in the neighborhood of a Masjid, and upon those who can normally hear the Adhan from their homes.

It is therefore, reprehensible to underestimate or ignore Salat al-Jama'at, and according to the Islamic rulings, it is not permitted to keep away oneself from the Salat al-Jama'at unduly, nor is it proper to abandon it without a justifiable excuse.

It is further Mustahab to wait for some time until the Salat al-Jama'at begins with the intention to participate in the Salat, since a short congregational Salat is better than a prolonged Salat offered alone. It is also better to wait for the Salat al-Jama'at to be established, even if it is offered after the prime time rather than to pray alone. In fact, if a person realizes that the Salat al-Jama'at has been established but he has already read his Salat, it is Mustahab to repeat the prayers again in Jama'at.

The Imam of the Jama'at stands in front of those who are following him. The followers are behind him, forming straight lines-each standing close to the other one's shoulders. As for the distance between the rows, according to Ihtiyat Mustahab, it should be just enough to allow the person to perform Sajdah.

When there are only two people in Salat al-Jama'at, the Imam and the Ma'mum, then it is Mustahab that the Ma'mum position himself just behind the Imam on his right side, although, he can also stand in line with the Imam. When there are many followers, according to Ihtiyat Wajib, the followers must not stand beside the Imam, rather they must be behind him.

The standing place of the Imam compared to that of the Ma'miim should not be higher than the span of four closed fingers. But the place where the followers stand could be higher than that of the Imam. Of course, the height must be reasonable enough to maintain the appearance of Salat al-Jama'at.

There must not be a large distance or obstruction between the Imam and the Ma'miim. If the Ma'miim is standing exactly behind the Imam, then his forehead in Sajdah should fall just behind the feet of the Imam. Similarly, there must not be any gap or obstruction between the lines.

If during the course of the Salat al-Jama'at, a person finds that he is distanced from the preceding line by a foot or more, then since he is isolated from the Jamaat, he should change his intention from Salat al-jamaat to Furada (single prayer) amd continue his prayers as such.

For the Imam: the Imam must consider the fact that some of the participants in the Jama'at may be weak or aged, and as such, he should avoid lengthy Surahs, Qunilt, Ruku', and Sujud. His pace must be moderate so as to suit followers of all ages.

In those Salat in which the Surahs are to be read aloud (Salat al-Fajr, Maghrib and 'Isha), the Imam is expected to raise his voice so as to become reasonably audible (heard by the followers).

When the Imam in Ruku' learns, that a newcomer wishes to join the Salat al-Jama'at, it is Mustahab for him to prolong his Ruku' to twice his usual duration, and then get up without waiting for another one who might want to join in.

For the Ma’mum: The lines should be straight, with each person standing close to another -shoulder to shoulder. As long as there is a gap in anyone line, that spot should be filled before making a new line, and it is Makruh for a person to stand alone. It is Mustahab that after the line is read, the followers rise and get ready to start the Salat. It is Makruh for the followers to recite any of the supplications, Tasbih or Takbir, in such a way that the Imam can hear them. When a Ma'mum wishes to join the Imam in Ruku ' ; but fears that the Imam may rise before he can join, he can make a polite appeal by saying signaling to the Imam that he wishes to join. After the signal, he should not waste any time and join otherwise it might inconvenience the other participants. He should then pronounce the Takbiratul Ihram loudly so the Imam becomes aware that the appellant has joined.

One who leads the prayers is called the Imam, and he must be:

Baligh (Adult) meaning that he has attained the age of responsibility and puberty; and for Men, it is one who has completed 15 lunar years, or has seen in himself the signs of puberty or adulthood.
Sane (' Aqil)
Shi'a Ithna ' Asheri (believes in the mastership of the 12 Imams)
Adil (Just) meaning that he does not commit the major or minor sins. 5. Legitimate birth.
Able to recite correctly.

A woman can lead the Salat only if all the followers are women; however, if all of the followers are men or there is a congregation of men and women, then the Imam must be a man.

Make the niyyat (intention) that you are praying behind and following the Imam who is leading the Salat. It is not necessary to know his name, however, you should know that you are following that particular Imam. Your Salat will not be counted as Salat al-Jamaat if you do not make the intention of following the Imam -this is important.

The follower must say the Takbiratul Ihram after the Imam, so as to maintain his Salat al Jamaat.

Listen to the Imam
In the first two Rak'at, the Imam will read Surah al-Fatiha and one more complete Surah of the Holy Qur' an. If you are praying the Salat of Fajr, Maghrib and 'Isha, then the Imam will be reciting these Surahs out loud, thus, you should keep silent, and listen to his recitation. In the Salat of Zuhr and ‘Asr, the Imam will be reciting in a quiet whisper and you will not recite anything out loud, however, it is Mustahab that you recite any Dhikr of Allah such as

Recite Everything Else in Jamaat
Apart from the two Surahs which the Imam alone will recite, you must independently recite all the other things in the Salat. You must pray the Dhikr of Ruku, Sujud, Tashahhud, Salam, and all the Takbirs, etc.

So remember, that a Ma'mum is exempted from reading only the two Surahs in the first two Rak'at.

Follow the Imam
As was previously mentioned, the Ma’mum must say the Takiratul Ihram (the first) after the Imam has said it. If you say it simultaneously with the Imam or before, then there will be no Jamaat for you.

Then, in every act, follow the Imam. When the Imam goes into Ruku ' Sujud, or rises, do it either with him or after him; but do not precede him. This is important as far as the acts are concerned. However, in the case of the recitations like the Dhikr in Ruku', Sujud, Qunut, etc., you may precede the Imam, even the Salam to complete the Salat.

If you forgetfully rise from Ruku' or Sujud before the imam, you must return to the Ruku ' or Sajdah position (as the case may be) provided that the Imam is still in that position.

You can join the Salat at any stage before the Imam rises from Ruku'. After the Imam has risen from Ruku', you will not be able to join him until he stands for the next Rakat.

You can not join the Imam while he is in Sajdah, nor can you join when the Imam stands up after completing the Ruku’.

Q. Can I join when the Imam is reciting the Second Surah?
A. Yes.

Q. Can I join when he is in Qunut?
A. Yes, you can join, and perform the Qunut as well.

Q. How do I join when the Imam is in Ruku '?
A. Make your intention, say the Takbiratul Ihram and go straight into Ruku'. This will be counted as your first Rak'at.

Q. How can I join when the Imam is in the third or fourth Rak'at?
A. In the third or fourth Rak'at, the Imam does not usually read Surah al- Fatiha nor is there a second Surah, he will usually recite Tasbihatul , Arbah. Therefore, if you join him while he is standing, you must read at least Surah al- Fatiha -you can not simply keep silent. Therefore, if you believe that you will be able to read at least Surah al-Fatiha before the Imam goes into Ruku' and rises, you may join while he is standing. However if you believe that al-Fatiha may take a longer time to read and that you may miss the Ruku ' with the Imam, then do not join while the Imam is standing. In this case, join him when he goes into Rukuii ' .It is always advisable to join the Salat al-Jama'at in Ruku' if the Imam is in the third of fourth Rak'at.

Q. If I joined Salat al-Jamaat in the third Rak'at of the Imam, then what do I read in the next Rak'at which will be my second, but the Imam 's fourth?
A. You will treat it as your second and read surah al-Fatiha and another Surah, and do your best to reach the Imam while in Ruku'. If you find that there would not be enough time for the second Surah and Qunut, then Surah al-Fatiha alone will suffice.

Q. Should my Salat be the same as the Imam's?
A. No, you can pray Salat al-Maghrib, for example, behind an Imam who is leading Salat al-'Isha, and vice versa.

Q. What happens if a young child is standing in one of the rows? Does our Salat become void?
A. No, as long as the child is a Mummayiz, meaning he can distinguish between good and bad, and as long as the people around him do not have knowledge if his Salat has become void, their Salat al-Jama'at is correct.

It is Mustahab to be present in Salat al-Jama'at from its very start. If fact, there is a great reward in being able to say the Takbiratul Ihram immediately after the Imam has said it, and before he commences the recitation of Surah al-Fatiha.

However, if due to some unavoidable circumstance, you reach late, then you will read as many Rak'at of Jama'at as available, and complete the balance on your own.

For example, if you reach Salat al-' Asr when the Imam is in his second Rak'at, then you will join, and when the Imam is in his last Rak'at, you will change your Salat to Furadah (single), and complete the remaining one Rak'at alone.

When it is your first Rak'at and the Imam's second, then according to Ihtiya1, after the two Sajdah, you must sit in a position, flexing your legs, keeping fingers and feet on the ground, and listen to the Tashahhud being recited by the Imam (this position is referred to as Tajafi).

Similarly, when it the last Rak'at of the Imam but you still have the balance to complete, it is Mustahab that you flex your legs with your fingers and feet still on the ground and wait until the Imam has finished reciting the Salam and then stand up to complete the Salat alone.

When a person arrives so late that he finds the Imam is in his last Tashahhud, he would still be able to obtain the reward of Jama'at. He should make the intention, say the Takbiratul Ihram and sit to join the Tashahhud. Then when the Imam has completed his Salat with the Salam, he should rise to begin the first Rak'at and he does not have to make the intention or say the Takbir again.

The first person standing directly behind the Imam in Salat al- Jama'at is connected to the Imam and so are the people next to him. However, as the first line extends, people standing further away fro~ the Imam are connected sideways.

Connections must always be maintained in Salat al-Jama'at, for if it breaks, then there will be no Salat al-Jama'at. For example, if a person standing in the second, third or any subsequent line loses all connection with no one in front of him or by his sides, his Salat al-Jama'at ceases to exist, and he must continue his Salat by means of Furadah. However, if he has someone by his either side who is in turn properly connected with someone else in front, then his Salat al-Jama'at will be valid.

If anyone is praying Salat al-Qasr, he should try to avoid standing in the first line, since if he chooses to remain seated after two Rak'at, he will become an obstruction to the people connected to him, rendering their Salat al-Jama'at invalid and void. However, if he immediately rises again to join Salat al-Jama'at, then the connection will be resumed and no harm is done to the other believers around him.

If a traveler prays in the second or any subsequent line, no harm will be done to the believers standing next to him even if he remains seated after the completion of two Rak'at. This is because people in the subsequent lines normally have more than one source of contact and connection.

# If the Imam's Salat becomes void due to any reason, the Ma'mum behind him may steadily step forward to lead, provided that he fulfills the qualifications for leading the Salat. Other followers will change their intention to follow the new Imam

# If no one goes forward to continue the Salat al-Jama'at, then the followers will convert their Salat to Furadah and complete the Salat on their own.

# If someone faints or collapses during the Salat al-Jama'at, then the people standing next to him may break their Salat to attend to him, provided that there is no one else to help him from amongst those who have not joined the Salat.

# If the Salat of anyone in the first line becomes void, he must get out of the line immediately. He must neither continue nor sit down, since it will be a distraction, and may render the Salat al-Jama'at of the others following him in the same line as void. When he moves out, there will be a gap, and thus the other people next to him must gradually move sideways to reduce or fill in the gap.

# If for any reason, the Salat al-Jama'at ceases to exist, the Ma'mum must not break their Salat, they must simply change the intention from Jama'at to Furadah and continue until completion.

# If due to some reason, the Ma'mum has to abandon the Salat al-Jama'at, then he can do so and change to Furadah. However, one cannot join the lama 'at with an intention of later breaking it.

Muslim women may join Salat al-Jama'at, but they will keep their position behind the men. Although in Salat al-Jama'at, no obstruction between the Imam and Ma'mun is permitted, the women are permitted to stand behind barriers such as a partition, wall, curtain, etc. and be part of the Salat al-Jama'at. The women are also permitted to have their own Salat al-Jama'at in which a lady Imam can lead -as long as there are only women in the Jama'at. However, she will not stand in front, but will position herself in the center of the first line, and those following her will form the first line by standing by her sides.

1]. The Holy Prophet, peace be upon him and his family, said: "Verily, when one of Allah's servants establishes the Salat in congregation and asks Him something which He does not grant him, Allah will be ashamed until He fulfills it.”

2]. Imam' Ali ibn Musa al-Riza, peace be upon him, said: "The excellence of the congregation Salat compared to a solitary Salat, is one Rak'at to two thousand Rak'at

3]. The Holy Prophet, peace be upon him and his family, said: "One prayer of a man in congregation is worthier than his forty years of prayers at home (alone).”

4]. Imam Muhammad al-Baqir, peace be upon him, said: "The person who abandons the congregation (Salat) without having an excuse, and only for unwillingness or in order to avoid attending the gathering of Muslims, has no Salat (his Salat will not be accepted).”

5]. Once a blind man came to the Prophet of Allah, peace be upon him and his family, and said that there was not anyone to take him to the Masjid to attend the congregational Salat with him (the Prophet), when he heard the call to prayer. The Holy Prophet, peace be upon him said, "Stretch a rope from your house up to the Masjid and attend the congregational Salat.

SOME MISTAKES AND THEIR EFFECTS ON SALATUL JAMAAT

`*` If during Salatul Jamaat, the Imam becomes incapable of leading the salat due to any reason, and the followers become aware of this situation, then the followers can continue their own salat with the niyyat of furada (individual) salat for the rest of the salat. But if some follower behind the Imam is capable of leading the salat, he can move forward to lead the salat from that point onward, and the followers will change their niyyat that they are praying rest of the salat behind this new Imam.

`*` If salat of only one follower in the Jamaat becomes invalid due to any reason, then the salat of other followers is not affected.

`*` If you were in standing (Qiyam) position and then went into ruku by mistake while Imam was still in Qiyam, then you must return to Qiyam position provided you are sure that Imam will still be reciting in Qiyam position after your return and if you did not return to Qiyam, your own salat is batil (invalid).

`*` If you went into Sajdah by mistake and found that Imam was still in sitting position, then you must go back to join Imam in that position.

`*` If you rise from ruku position by mistake before the Imam, then you must return to ruku position provided the Imam is still in that position. But if you return to the ruku position with the impression that the Imam was still in ruku, but actually by that time the Imam has risen from ruku, then according to Ayatullah Khui, your own salat is batil (invalid) (and hence you have to repeat your salat), and according to Ayatullah Seestani, your own salat is batil (invalid) with Ihtiyate Wajib. (Note: If your own salat becomes batil, then, if some rakats of salatul jamaat are still to be completed by the Imam, then you can re-join the salat with fresh Niyyat and Takbeer in the Qiyam or ruku of the next rakat of the Imam).

`*` If you were in first sajdah position of a rakat, and raised your head by mistake before the Imam, then you must return to sajdah to join the Imam provided the Imam is still in sajdah position. But if, by the time you returned to sajdah, the Imam had raised his head from Sajdah, then your salat is OK (but you have to do Sajdah Sahaw after the salat due to that extra sajdah). But if you repeat the same mistake while performing the second sajdah of the same rakaat, then your own salat is batil (invalid).

`*` If an Imam can only offer salat in sitting position (due to illness or other reasons), the he can not lead salat for followers offering salat in normal positions.

THINGS WHICH ARE MAKROOH IN SALATUL JAMAAT

(1) Joining in the back row by a follower if there is still space available for him in the front row. (It is recommended that the size of the rows in jamaat should be properly balanced as much as possible).
(2) Reciting of zikr of sajdah and ruku by a follower so loudly that Imam can hear it.
(3) Leading the salat by an Imam, whose salat is Qasr (i.e. 2-rakat zohr, asr or isha, shortened due to him being a traveller), for the followers, whose salat are not qasr. But this rule is relaxed when there is no one else available to lead or when an alim of a higher status is leading the salat.

SALATUL JAMAAT FOR TRAVELLERS

If your salat was Qasr (i.e. 2-rakat wajib salat shortened due to travelling), then you can join the normal salatul jamaat to offer your 2-rakat qasr salat, but you should better avoid standing in the first row of salatul jamaat (because your salat is shorter than the normal full salat of the jamaat). You may stand in other rows or at the end of any row.
If you are offering a 2-rakat qasr salat (such as zohr, asr or isha) with a 4-rakat full salatul jamaat, starting from the first rakaat of the Imam, then after 2nd rakat, you will finish your salat with salam. Then, in order to maintain continuity in the salat, it is better if you stand up and offer another 2-rakat wajib salat (e.g. with niyyat of your qaza or qaza of your dead relative) by joining the Imam in the next ruku, and following the usual rule of salatul jamaat.
