‘Abdallah b. Arqam said he heard God’s Messenger say, “When the time for prayer comes and one of you needs to relieve himself, he should do that first.”
Tirmidhi transmitted it, and Malik, Abu Dawud and Nasa’i transmitted something similar.
Ibn ‘Abbas reported God’s Messenger as saying, “If any one hears him who makes the call to prayer and is not prevented from joining the congregation by any excuse,” (he was asked what an excuse consisted of and replied that it was fear or illness), “the prayer he says will not be accepted from him.”
Thauban reported God’s Messenger as saying, “There are three things which are unlawful for anyone to do. A man must not act as imam for others in prayer and make a supplication for himself excluding them, for if he does that he has acted treacherously towards them. No one must look inside a house before asking permission to enter, for if he does so he has acted treacherously towards . And no one should pray while retaining urine, but should first relieve himself.”
Abu Dawud transmitted it, and Tirmidhi has something similar.
Abud Darda’ reported God’s Messenger as saying, “If there are three men in a village or in the desert among whom prayer is not arranged, the devil has got the mastery over them. So observe prayer in company, for the wolf eats only the straggling animal.”
