Sayyiduna Abdullah bin Amr (may Allah be pleased with them both) narrates: One day I was with the Messenger of Allah (peace and blessings be upon him) in his house (peace and blessings be upon him), and he (peace and blessings be upon him) said: "Do you know who is with us in the house?" I said: Who, O Messenger of Allah? He (peace and blessings be upon him) said: "Jibril (peace be upon him)." I said: As-salamu alayka ya Jibril wa rahmatullah (Peace be upon you, O Jibril, and the mercy of Allah). The Messenger of Allah (peace and blessings be upon him) said: "He has returned your greeting."
