Hazrat Abdullah bin Salam narrates that when the Messenger of Allah (peace and blessings be upon him) arrived in Madinah, people hurried to meet him. He says that I also came to the Messenger of Allah (peace and blessings be upon him). When I looked at him, I recognized that indeed his face was 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 this: He said, "O people! Spread peace, and maintain ties of kinship, and feed others, and pray at night while people are sleeping."
