Thuwayr bin Abi Fakhitah narrates from a Companion of the Prophet (peace and blessings be upon him) whose name was Sayyiduna Abu al-Khattab (may Allah be pleased with him): He asked the Prophet (peace and blessings be upon him) about the witr, and the Prophet (peace and blessings be upon him) said: Would you like me to perform the witr at midnight? Indeed, Allah Almighty descends (at midnight) from the uppermost heaven to the lowest heaven and says: Is there anyone asking? Is there anyone seeking forgiveness? Is there anyone supplicating? (The Prophet (peace and blessings be upon him) said:) This continues until true dawn; when true dawn appears, He ascends.
Imam al-Tabarani recorded this narration in al-Mu'jam al-Kabir, and the narrator Thuwayr is da'if (weak).
