Ibn ‘Umar said that some of the Prophet’s companions had a dream that lailat al-qadr was among the last seven nights, so God’s messenger said, “ I see that your dreams agree regarding the last seven nights, so if anyone seeks it he should do so during the last seven nights.”
Ibn ‘Abbas reported the Prophet as saying, “Seek lailat al-qadr in the last ten nights of Ramadan, on the twenty-first, twenty-third and twenty-fifth.”
Buraida said that once when Bilal went in to visit God’s messenger while he was having his morning meal he invited him to join him, and when Bilal replied that he was fasting, he said, “We are eating our provision and Bilal’s superior provision is in paradise. Did you know, Bilal, that the bones of one who fasts extol God and that the angels ask forgiveness for him as long as people eat beside him?”
