Narrated Abu Dharr: We fasted with the Messenger of Allah صلی اللہ علیہ وسلم during Ramadan, but he did not make us get up at night for prayer at any time during the month till seven nights remained; then he made us get up for prayer till a third of the night had passed. When the sixth remaining night came, he did not make us get up for prayer. When the fifth remaining night came, he made us stand in prayer till a half of the night had gone. So I said: Messenger of Allah, I wish you had led us in supererogatory prayers during the whole of tonight. He said: When a man prays with an imam till he goes he is reckoned as having spent a whole night in prayer. On the fourth remaining night he did not make us get up. When the third remaining night came, he gathered his family, his wives, and the people and prayed with us till we were afraid we should miss the falah (success). I said: What is falah? He said: The meal before daybreak. Then he did not make us get up for prayer during the remainder of the month.

Narrated Aishah: When the last ten days of Ramadan came, the Prophet صلی اللہ علیہ وسلم kept vigil and prayed during the whole night, and tied the wrapper tightly, and awakened his family (to pray during the night). Abu Dawud said: The name of Abu Ya'fur is Abdur-Rahman bin Ubaid bin Nistas.

Zirr (b. Hubaish) said: I said to Ubayy bin Kab: Tell me about lailat al-qard, O Abu al-Mundhir, for our companion (Ibn Masud) was questioned about it, and he said: Anyone who gets up for prayer every night all the year round will hit upon it (i. e. lailat al-qadr). He replied: May Allah have mercy on Abu Abdur-Rahman. By Allah, he knew that it was in Ramadan, (Musaddad's version goes) bu he disliked that the people should content themselves (with that night alone) ; or he liked that the people should not content themselves (with the night alone). According to the agreed version: By Allah, it is the twenty-seventh night of Ramadan, without any reservation. I said: How did you know that, Abu al-Mundhir ? He replied: By the indication (or sign) of which the Messenger of Allah صلی اللہ علیہ وسلم informed us. I asked Zirr: What is the sign ? He replied: The sun rises like a vessel of water in the morning following that night ; it has no ray until it rises high up.
