The blessed wife of the Prophet (peace be upon him), Lady Aisha (may Allah be pleased with her), said: The Messenger of Allah (peace be upon him) said: "O Aish! This is Jibreel (peace be upon him) who is conveying greetings of peace to you." Lady Aisha (may Allah be pleased with her) said: "And peace, mercy, and blessings of Allah be upon him."
She said: And the Prophet (peace be upon him) was seeing what I was not seeing (i.e., Jibreel, peace be upon him).
