Musannaf Ibn Abi Shaybah 8909 — Laylat al-Qadr and which night it is

Sayyiduna Abdullah (bin Mas'ud) (may Allah be pleased with him) said: Seek Laylat al-Qadr in the 23rd, 21st and 19th nights of Ramadan, (the last being) the morning of Badr. For the sun rises every day between the two horns of Satan, except on the morning of Badr, for then the sun rises white and has no rays.
