Al-Adab Al-Mufrad #707

Anas said, "I was with the Prophet, may Allah bless him and grant him peace, when a man made supplication, saying, 'O Originator of the heavens! O Living, Self-Subsistent! I ask of You.' He said, 'Do you know by what he has made supplication? By the One in whose hand my soul is, he has asked Allah by the Name that He answers when He is asked by it."
