It is narrated from Sayyiduna Abu Hurairah (may Allah be pleased with him) that a man passed by the Messenger of Allah (peace and blessings be upon him) while he was sitting in a gathering. He said: «السلام علیکم» . The Prophet (peace and blessings be upon him) said: "Ten good deeds (were written for him)." Then another man passed by and he said: «السلام علیکم ورحمۃ اللہ» ! The Prophet (peace and blessings be upon him) said: "(For him) there are twenty good deeds." Then a third man passed by and he said: «السلام علیکم ورحمۃ اللہ وبرکاتہ» ! Then the Messenger of Allah (peace and blessings be upon him) said: "(He) received thirty good deeds." Then a person got up from the gathering and left without saying salam, so the Messenger of Allah (peace and blessings be upon him) said: "How quickly your companion forgets! When any of you comes to a gathering, let him say salam. If he thinks it appropriate, let him sit down, and when he gets up, let him say salam, for the first salam is not more important than the second."

It is narrated from Sayyiduna Umar (may Allah be pleased with him) that I was riding behind Sayyiduna Abu Bakr (may Allah be pleased with him). Whenever he passed by any people, he would say: «السلام علیکم» and the people would reply: «السلام علیکم ورحمۃ اللہ» . Sayyiduna Abu Bakr (may Allah be pleased with him) would say: «السلام علیکم ورحمۃ اللہ» and they would say: «السلام علیکم ورحمۃ اللہ وبرکاتہ» . Sayyiduna Abu Bakr (may Allah be pleased with him) said: Today, people have surpassed us greatly in virtue.

Through another chain, it is also narrated from Sayyiduna Umar (may Allah be pleased with him) in a similar manner.

Narrated from Sayyidah Aisha (may Allah be pleased with her) that the Messenger of Allah (peace and blessings be upon him) said: "The Jews are not as jealous of anything from you as they are of your greeting of Salam and saying Ameen."
