Musannaf Ibn Abi Shaybah 8904 — Laylat al-Qadr and which night it is

Sayyiduna Ibn Abbas (may Allah be pleased with them both) said: Once in Ramadan I was asleep when a man came to me and said: "Tonight is Laylat al-Qadr." I got up still drowsy, and holding on to a rope of one of the tents of the Prophet (peace and blessings be upon him), I came to him, and he was praying. I estimated the night, and it was the 23rd night of Ramadan.
Sayyiduna Abdullah bin Abbas (may Allah be pleased with them both) said: Satan comes out with the sun every night except Laylat al-Qadr. That is why, on the day of Laylat al-Qadr, the sun rises white, without rays.
