Allah’s Messenger صلى الله عليه وسلم said, “Our Rabb, the Blessed and Superior, comes down every night to the nearest Heaven to us when the last third of the night remains, saying: “Is there anyone to invoke Me, so that I may respond to invocation? Is there anyone to ask Me, so that I may grant him his request? Is there anyone seeking My forgiveness, so that I may forgive him?”

Sahih Bukhari, Narrated by Abu Huraira
