Disappearance of a Muslim

227. When body or dress or anything else such as household utensil or carpet which has been in the possession of a Muslim becomes Najis, and thereafter that Muslim disappears, the things in question can be treated as Pak, with the following six conditions:

1. That Muslim should believe in the Najasat of an object which made his body or dress Najis. For example, if his dress becomes Najis with the sweat of a person who has become Mujnib by committing Haraam act, and he does not believe that sweat to be Najis, his dress will not be deemed Pak after his disappearance.
2. That Muslim should know that his body or dress has touched a Najis thing.
3. That the man should have been seen using that thing for a purpose which requires it being Pak. For example, he should have been seen offering prayers with that dress.
4. That the Muslim knows that the condition for the act he wants to perform is to be Pak. For example, if he does not know that the dress of one who offers prayers should be Pak, and he offers prayers with a Najis dress, that dress cannot be considered to be Pak.
5. There should be an assumption that the Muslim has washed the thing which has become Najis. So, if one is sure that a Najis thing has not been washed, one should not consider it as Pak. And also, if that Muslim is careless about the difference between Najis and Pak, considering his things to be Pak is a matter of Ishkal.
6. That the Muslim, as per obligatory precaution, should be Baligh (Mature).

 228. If a person becomes satisfied that a thing which was Najis has become Pak, or if two just persons testify regarding the thing being Pak, then that thing is considered Pak. And similarly, when a person who possesses the Najis thing, reliably says that it has become Pak, or when a Muslim has washed the Najis thing with water, even if it may not be known whether or not he has washed it properly, the thing will be considered Pak.

229. If a person undertakes the responsibility to wash and make Pak the dress of another person and confirms having washed it, and if the other person is satisfied with what he is told, the dress is Pak.

230. If a person is in such a mental state that he can never be certain about a Najis thing becoming Pak, his guess of becoming that thing as Pak is sufficient.
