‘Abdullah bin Salam said: “When the Prophet (ﷺ) came to Al-Madinah, the people rushed to meet him, and it was said: ‘The Messenger of Allah (ﷺ) has come! The Messenger of Allah (ﷺ) has come! The Messenger of Allah (ﷺ) has come!’ Three times. I came with the people to see him, and when I saw his face clearly, I knew that his face was not the face of a liar. The first thing I heard him say was when he said: ‘O people! Spread (the greeting of) Salam, feed others, uphold the ties of kinship, and pray during the night when people are sleeping, and you will enter Paradise with Salam.”*
‘Abdullah bin ‘Umar used to say that the Messenger of Allah (ﷺ) said: “Spread (the greeting og) Salam, offer food (to the needy), and be brothers as Allah, the Mighty and Sublime, has honored you.”
It was narrated from ‘Abdullah bin ‘Amr that a man asked the Messenger of Allah (ﷺ): “O Messenger of Allah, which (aspect) of Islam is the best?” He said: “Offering food (to the needy) and greeting with Salam those whom you know and those whom you do not know.”
