Mishkat al-Masabih #1818

‘Abdallah b. Salam said: When the Prophet came to Medina and I went and examined his face, I recognised that it was not the face of a liar. The first thing he said was, “If you people greet all whom you meet, provide food, care for the wellbeing of your kindred, and pray at night when people are asleep, you will enter paradise in peace.’’ Tirmidhi, Ibn Majah and Darimi transmitted it.
