Musnad Ahmad 1098:5

Yahya ibn Sa'id narrated to us, from 'Awf, Zurarah narrated to us, he said: Abdullah ibn Salam said—and Muhammad ibn Ja'far narrated to us, 'Awf narrated to us, from Zurarah, from Abdullah ibn Salam, he said: When the Prophet, peace and blessings of Allah be upon him, arrived, the people rushed toward him, and I was among those who rushed. When I clearly saw his face, I knew that his face was not the face of a liar. The first thing I heard him say was: "Spread peace, feed the hungry, maintain kinship ties, and pray while the people are asleep; you will enter Paradise in peace."
