Mishkat al-Masabih #1997

‘A'isha said she asked God’s messenger to tell her what prayers to say on lailat al-qadr if she knew which night it was, and he told her to say, “O God, Thou art forgiving and lovest forgiveness, so forgive me.” Ahmad, Ibn Majah, and Tirmidhi transmitted it, and Tirmidhi declared it to be sound.
