Laylatul Qadr

Aisha related that the Prophet said: Look for Lailat al-Qadr on an odd-numbered night during the last ten nights of Ramadan (Bukhari).

Ubaadah bin Saamit (Radhiallaho anhu) reports that he asked the Prophet (Sallallaahu alaihi wasallam) about"Laylatul Qadr". He replied: "It is in Ramadan, during the last ten days, on the unevenly numbered nights, either the 21st 23rd, 25th, 27th, 29th or the last night of Ramadan. Whosoever stands in "Ibaadah" on this night, with sincere faith and with genuine hopes of gaining reward, his previous sins will be forgiven.

Among the signs of this night is that it is a serene, quiet, shining night, neither hot, nor cold but temperate as if a moon is shining clear, and no meteors are shot at the "Shayateen" on that night; it lasts until the break of the dawn. Another sign is that at morn, the Sun rises without any radiant beams of light, appearing rather like the moon in it's fullness. On that day, Allah prohibits the "Shayateen" from rising up with the Sun."

Aaisha (RadhiAllaho anha) reports: "I said: 'O Messenger of Allah (Sallallaahu alaihi wasallam), should I find myself the "Laylatul Qadr", what shall I pray. The Prophet (Sallallaahu alaihi wasallam) replied: say, Allaahumma innaka afuwwun tohibbu al'afwa fa'fu anna (O Allah, Thou art the One who grants pardon for sins. Thou lovest to
pardon, so O pardon me.)
