Musannaf Ibn Abi Shayba 34:115

Abu Usama narrated to us, from Awf, from Zurara ibn Awfa, that Abdullah ibn Salam narrated to us. He said: When the Messenger of Allah (peace be upon him) arrived in Medina, the people rushed towards him, and it was said: "The Messenger of Allah (peace be upon him) has arrived," three times. So I came among the people to look at him. When I clearly saw his face, I knew that his face was not the face of a liar. The first thing I heard him speak was when he said: "O people, spread peace, feed the hungry, maintain family ties, and pray while the people are sleeping; you will enter Paradise in peace."
