Musannaf Ibn Abi Shaybah 8902 — Laylat al-Qadr and which night it is

Abu Marthad said: I was with Sayyiduna Abu Dharr al-Ghifari (may Allah be pleased with him) at the middle Jamrah. I asked him about Laylat al-Qadr, and he said: "I was the one who asked the Messenger of Allah (peace and blessings be upon him) about Laylat al-Qadr more than anyone. One day I said: 'O Messenger of Allah, Laylat al-Qadr occurs in the times of the prophets, and when the prophets departed from the world this night was also taken up; is that so?' He said: 'No, rather Laylat al-Qadr will remain until the Day of Resurrection.' I said: 'O Messenger of Allah, then tell me about it.' He said: 'If I had been permitted to tell about it, I would certainly have told you. However, I will say this much: seek it in one of the last seven nights of Ramadan. Now do not ask me about this.' After that he (peace and blessings be upon him) became occupied with other matters. When I sensed that he was in a cheerful mood, I said: 'O Messenger of Allah, I adjure you to tell me about this night.' On hearing this, he (peace and blessings be upon him) became so angry with me that I never saw him so angry before or after."
