Narrated Abu Huraira, Prophet of Allah (Sallallāhu alayhi wa sallam) said:
"Every night when it is the last third of the night, our Lord, the Superior, the Blessed, descends to the nearest heaven and says: Is there anyone to invoke Me that I may respond to his invocation? Is there anyone to ask Me so that I may grant him his request? Is there anyone asking My forgiveness so that I may forgive him?."
[Sahih Bukhari - Book #93, Hadith #586]
