 252. Jabir bin ´Abdullah narrated that the Messenger of Allah salla alayhi wa sallam said: ´´He who eats garlic or onion, should keep away from us, (or: keep away from our mosque) let him stay at his home.´´ (Jabir bin ´Abdullah in another narration said:) Once a big pot containing cooked vegetables was brought. On smelling unpleasant odor coming from it, the Prophet salla alayhi wa sallam asked, ´´What is in it?´´ He was told all the names of the vegetables that were in it. The Prophet salla alayhi wa sallam ordered that it should be brought near to one of his Companions who were with him. When the Prophet salla alayhi wa sallam saw, he disliked to eat it, he said: ´´Eat. (I don´t eat) for I usually have private talk with those whom you don´t (i.e., the angels).´´

 248. Abu Qatadah narrated: I entered the mosque, when the Messenger of Allah salla alayhi wa sallam was sitting with people, i sat down with them. The Messenger of Allah salla alayhi wa sallam asked: ´´What prevented you from performing two Rak´ah before sitting down?´´ I said: ´´O Messenger of Allah! I saw you sitting and people were sitting.´´ He said: ´´When one of you enters the mosque, let him not sit before he performs two Rak´ah.´´

 247. Abu Hurairah (Or: Abu Usaid) narrated that the Messenger of Allah salla alayhi wa sallam said: ´´When one of you enters a mosque, let him say: ´O Allah! open for me the door of Your mercy.´ And when he steps out, let him say: ´O Allah! I ask you of Your bounty.´´´
