Hazrat Abdullah bin Salam narrates that when the Messenger of Allah (peace and blessings be upon him) arrived in Madinah, people hurriedly came to his service and it was being said that the Messenger of Allah (peace and blessings be upon him) has arrived. He says that I also came along with the people so that I could see the Messenger of Allah (peace and blessings be upon him). When I saw the radiant face of the Messenger of Allah (peace and blessings be upon him), I recognized that surely this face is not the face of a liar, and the very first thing I heard the Messenger of Allah (peace and blessings be upon him) say was: "O people! Spread peace (salaam)."
