It was narrated that Abdullah bin Salam said: "When the Messenger of Allah ﷺ came to Al-Madinah, the people rushed towards him and it was said: The Messenger of Allah ﷺ has come! I came along with the people to see him, and when I looked at the face of the Messenger of Allah, I realized that his face was not the face of a liar. The first thing he said was: "O people, spread (the greeting of) Salam, offer food to people and pray at night when p people are sleeping, you will enter Paradise in peace." (Sahih)
