It is narrated from Sayyiduna Hudhayfah bin Yaman (may Allah be pleased with him) that the Noble Prophet (peace and blessings of Allah be upon him) said: "When a believer meets another believer, greets him with salam, and shakes hands with him, their sins fall away like the leaves of a tree."

It is narrated from Sayyiduna Abdullah (may Allah be pleased with him) that the Noble Prophet (peace and blessings of Allah be upon him) said: «سلام» is the name of Allah, which He has sent down to the earth, so spread it among yourselves. When a Muslim man passes by a group and greets them with salam, and they reply to his salam, then the one who greeted has superiority over them. And if they do not reply, then such (beings) reply to him who are better and purer than them.

It is narrated from Sayyiduna Abdullah bin Umar (may Allah be pleased with them both) that he said: The Messenger of Allah (peace and blessings be upon him) said: "Greeting (salam) comes before asking a question. Whoever starts asking a question before greeting, do not fulfill his request."

Sayyiduna Anas bin Malik (may Allah be pleased with him) says that the Messenger of Allah (peace and blessings be upon him) would pass by children, greet them with salam, and pray for blessings for them.
