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."
