Musannaf Ibn Abi Shaybah 9762 — The last ten days of Ramadan

Abu Aqrab al-Asadi said: We came to Sayyiduna Ibn Mas'ud (may Allah be pleased with him) and found him on the roof of the house. We heard him saying, before he came down: "Allah and His Messenger spoke the truth." We said to him: "We heard you say, before you came down, 'Allah and His Messenger spoke the truth.'" Sayyiduna Abdullah bin Mas'ud (may Allah be pleased with him) said: "Laylat al-Qadr is in the middle of the last seven nights. Its sign is that on that day the sun rises white, without rays. When I looked at the sun, I found it just as I had been told, so I proclaimed the greatness of Allah out of joy."
