The Messenger of Allah said: “If you see a man frequenting the mosques, then bear witness to his faith. Allah says: ‘The mosques of Allah shall be maintained only by those who believe in Allah and the Last Day. ‘”
“When Ka’b was dying, Umm Bishr bint Bara’ bin Ma’rur came to him and said: ‘O Abu ‘Abdur-Rahman! If you meet so-and-so, convey Salam to him from me.’ He said: ‘May Allah forgive you, O Umm Bishr! We are too busy to think of that.’ She said: ‘O Abu ‘Abdur-Rahman! Did you not hear the Messenger of Allah (ﷺ) say: “The souls of the believers are in green birds, eating from the trees of Paradise”?’ He said: ‘Yes.’ She said: ‘That is what I mean.’”
“Every good deed of the son of Adam will be multiplied manifold. A good deed will be multiplied ten times up to as many as seven hundred times, or as much as Allah wills. Allah says: ‘Except for fasting, which is for Me and I shall reward for it. He gives up his desire and his food for My sake.’ The fasting person has two joys, one when he breaks his fast and another when he meets his Lord. The smell that comes from the mouth of a fasting person is better before Allah than the fragrance of musk.”
