Musnad Ahmad 32:265

Waki' narrated to us, Abu Khuzaymah narrated to me, from Anas ibn Sirin, from Anas ibn Malik, that the Prophet (peace and blessings of Allah be upon him) heard a man saying: "O Allah, I ask You by the fact that to You belongs all praise, there is no god but You, You alone, having no partner, the Bestower, the Originator of the heavens and the earth, the Possessor of Majesty and Honor." The Prophet (peace and blessings of Allah be upon him) said: "You have asked Allah by His Greatest Name, which, if He is called upon by it, He answers, and if He is asked by it, He gives."
