What did the Prophet Muhammad (saw) say to `Aisha when he saw Gabriel?
 Narrated Abu Salama:                     `Aisha said that the Prophet said to her "O `Aisha' This is Gabriel and he sends his (greetings) salutations to you." `Aisha said, "Salutations (Greetings) to him, and Allah's Mercy and Blessings be on him," and addressing the Prophet she said, "You see what I don't see."
