It is narrated from Sayyidah Aishah (may Allah be pleased with her) that she said: Revelation came down upon the Prophet (peace and blessings be upon him) while I was with him (peace and blessings be upon him), so I closed the door between myself and him (peace and blessings be upon him). When the revelation ended, he (peace and blessings be upon him) said: "O Aishah, Jibril is conveying his greeting of peace to you."
