Narrated Anas ibn Malik: I was sitting with the Messenger of Allah صلی اللہ علیہ وسلم and a man was offering prayer. He then made supplication: O Allah, I ask Thee by virtue of the fact that praise is due to Thee, there is no deity but Thou, Who showest favour and beneficence, the Originator of the Heavens and the earth, O Lord of Majesty and Splendour, O Living One, O Eternal One. The Prophet صلی اللہ علیہ وسلم then said: He has supplicated Allah using His Greatest Name, when supplicated by this name, He answers, and when asked by this name He gives.

Narrated Buraydah ibn al-Hasib: The Messenger of Allah صلی اللہ علیہ وسلم heard a man saying: O Allah, I ask Thee, I bear witness that there is no god but Thou, the One, He to Whom men repair, Who has not begotten, and has not been begotten, and to Whom no one is equal, and he said: You have supplicated Allah using His Greatest Name, when asked with this name He gives, and when supplicated by this name he answers.
