Taharat & Najasat:
Ritual Purity & Impurity
Questions and Answers
  -  Question: The earth is one 
    of the purifying agents. Following the example of a shoe's sole that can be 
    purified by walking on the earth, would the same rule apply to car tires? 
    
 
 Answer: The earth cannot purify the tires.
 
 
-  Question: Where does the domino effect 
    of mutanajjis items stop when it is no longer wet?1
 
 Answer: The first mutanajjis item would 
    make the item that comes into contact with it impure; similarly, the second 
    mutanajjis would make the item that comes into contact with it impure; but 
    the third mutanajjis can no longer make other items impure, irrespective of 
    whether it is wet or dry.
 
 
-  Question: If a dog licks my body or 
    clothes, how should I purify it? 
 
 Answer: It is sufficient to wash it once. 
    However, if the water is little, it is necessary to rid it of the water by 
    wringing.
 
 
-  Question: Are the Sikhs considered 
    to be among the followers of the past revealed religions like the Jews and 
    the Christians? 
 
 Answer: They are not counted among the 
    People of the (Revealed) Books (the Ahlul Kitab).
 
 
-  Question: Are the Bhuddhists among 
    the Ahlul Kitab?
 
 Answer: They are not from them.
 
 
-  Question: Can Muslim, who rents a fully 
    furnished house in the West, consider everything in it to be ritually pure 
    as long as he does not find any trace of impure things in it, even if the 
    previous occupant was from Ahlul Kitab, i.e., a Christian or a Jew? What if 
    the previous occupant was a Bhuddhist or an atheist who does not believe in 
    God and the prophets?
 
 Answer: Yes, he can consider everything 
    in the house ritually pure as long as he does not know that it has become 
    impure. Just conjecture or doubt about impurity is of no value.
 
 
-  Question: The floor of most houses 
    in the West is covered with carpet which is glued to the floor in such a way 
    that it is difficult to lift it off. How can such a carpet be rendered pure 
    (tahir), if it becomes impure with urine or blood? The water used to purify 
    in both the cases could be qalil or kathir. Please explain the ruling in both 
    cases.
 
 Answer: If it is possible to wipe the 
    water off the carpet by using a piece of cloth or a vacuum cleaner, it can 
    be purified with qalil water, provided that the water is wiped off the carpet, 
    in the process. Conversely, it must be purified by kathir water [i.e., by 
    using a hose pipe connected to the tap].
 
 
-  Question: In the West, there are many 
    public laundry places in which Muslims and non-Muslims wash their clothes. 
    Is it permissible for us to pray in the clothes washed in such facilities, 
    especially when we have no knowledge whether or not the washing machines are 
    connected to the kurr water2 
    at some stages of the washing, and whether or not it purifies the clothes 
    in the process of washing?
 
 Answer: There is no problem in praying 
    in those clothes that were pure before washing them [in such facilities] as 
    long as you are not aware that they have become impure. [In other words, what 
    goes in the public washing machine as pure comes out as pure unless you are 
    sure that it has become impure.]
 Similarly, [you can pray in] the impure clothes [that were washed in the public 
    laundry machines] provided that you are reassured:
 
 
      -  that the impure element, if any, has been washed away;
 
 
-  that the pure water covered the entire impure area twice (if 
        it had become impure by urine and even if the water was connected to kurr 
        source as an obligatory precaution) or just once (if it had become impure 
        by other elements);
 
 
-  and that the water was removed from the clothes by wringing 
        or other similar method [i.e., spinning of the machine] if it was qalil.
 However, if you are not sure and just have conjecture that the garment 
        has been purified as per religious requirement, the previously impure 
        garment will still be considered impure and praying in it would not be 
        valid.
 
 
 
-  Question: Can the clothes washed with 
    liquid detergent in laundry facilities owned by a non-Muslim be considered 
    tahir while knowing that Muslims as well as non-Muslims wash their clothes 
    there?
 
 Answer: If you do not know that the clothes 
    have come into contact with a source of najasah, you can consider them tahir 
    (pure).
 
 
-  Question: Some soaps contain pigs' 
    fat or other animals not slaughtered Islamically. Furthermore, we do not know 
    whether or not chemical change has taken place in the manufacturing process. 
    Can such soaps be considered tahir? [Chemical change is a purifying agent 
    in the sense that it purifies a najis item.]
 
 Answer: If it is proven to contain those 
    [impure] elements, it should be considered impure, except if the occurrence 
    of chemical change is proven. Such a change is not proven in manufacturing 
    of soaps.
 
 
-  Question: A toothbrush that contains 
    bristles from the hair of a pig: is it permissible to buy, sell and use it? 
    Does the mouth become impure by using such a toothbrush?
 
 Answer: It is permissible to buy, sell 
    and use it; however, the mouth will become impure by using it; and the mouth 
    will become pure by taking that toothbrush out and getting rid of the remaining 
    toothpaste from the mouth.
 
 
-  Question: If blood is seen in the yolk 
    or the white part of the egg, does it make the egg impure and haram for us? 
    Is there a solution for it?
 
 Answer: The clot of blood inside the egg 
    is pure, but it is haram [for consumption]. Therefore, the egg can be eaten 
    by removing the blood from it, provided it not very minute and been absorbed 
    in it. [In the latter case, is not removable, then the egg becomes haram.]
 
 
-  Question: Are alchoholic beverages 
    pure? Is beer pure?
 
 Answer: There is no doubt about the impurity 
    of alchoholic drinks. As far as beer (fuqa') is concerned, it is impure on 
    the basis of precaution; however, there is no doubt in it being haram.
 
 
-  Question: The people residing in Europe 
    are of different faiths, nationalities and religions; and when we buy moist 
    or wet food items, the shopkeeper may touch it with his hands. Since we do 
    not know his religion, can we consider that food as pure?
 
 Answer: As long as it is not known that 
    the hands of the shopkeeper were najis, the food is to be considered tahir.
 
 
-  Question: What about the leather products 
    made in a European country, if we are unaware of the source of that leather? 
    It is said that some European countries import cheap leather from Muslim countries 
    and then use it for manufacturing various products. Can we consider such leather 
    pure? Are we allowed to say salat in them? Can such a weak probability [about 
    it originating from a Muslim country] be given any credence?
 
 Answer: If the probability of the leather 
    originating from a zabiha (an animal slaughtered Islamically) source is so 
    weak that people would not normally give any credence (for example, the probability 
    of 2%), it is to be considered impure and this cannot be used in salat. But 
    if the probability is not so weak, it can be considered pure and using it 
    in salat would be permissible.
 1. Translator's Note: An item 
  which is impure by itself is known as 'ayn najis or simply najis; the item that 
  becomes impure by coming into wet contact with an 'ayn najis is known as "mutanajjis," 
  that is impure by secondary reason.
 2. Translator's Note: All 
  laundry machines are connected to kurr source because it comes from the main 
  reservior supplying the water to the city.
