Aishah narrated: "I could not find the Messenger of Allah one night. So I left and found him at Al-Baqi. He said: 'Did you fear that you had been wronged by Allah and His Messenger?' I said: 'O Messenger of Allah! I thought that you had gone to one of your wives.' So he said: 'Indeed Allah, Mighty and Sublime is He, descends to the lowest Heavens during the night of the middle of Sha'ban, to grant forgiveness to more than the number of hairs on the sheep of (Banu) Kalb.'"
