It is narrated from Sayyiduna Abu Darda (may Allah be pleased with him) that the Noble Prophet (peace and blessings be upon him) said: "When two Muslim men are walking together and (while walking) a tree or a stone or a building (or a mound) comes between them, then (as soon as they meet again) they should greet each other with salam."

It is narrated from Sayyiduna Abu Hurairah (may Allah be pleased with him) that the Messenger of Allah (peace and blessings be upon him) said: "When one of you meets his brother, he should greet him with salam. If a tree, wall, or stone comes between them and then they meet again, he should greet him with salam once more."

It is narrated from Sayyiduna Abdullah bin Amr (may Allah be pleased with them both), he says that the Messenger of Allah (peace and blessings be upon him) said: "Worship the Most Merciful, feed (others), and spread the greeting of peace widely; you will enter Paradise in peace."

Sayyiduna Abu Hurairah (may Allah be pleased with him) narrates that the Messenger of Allah (peace and blessings be upon him) said: "The most helpless person is the one who is unable to make supplication, and the most miserly person is the one who is miserly in greeting (with salam)."

It is narrated from Sayyiduna Bara’ (may Allah be pleased with him) that the Noble Prophet (peace and blessings of Allah be upon him) said:“Spread salam (greetings of peace) widely, you will live in peace.”

It is narrated from Sayyiduna Abdullah bin Umar (may Allah be pleased with them both) that the Messenger of Allah (peace and blessings be upon him) said: "Spread peace widely, feed others, and become brothers as Allah has commanded you."

Zararah bin Awfi narrates that Abdullah bin Salam (may Allah be pleased with him) told me that when the Prophet Muhammad (peace and blessings be upon him) arrived in Madinah, people rushed towards him and it began to be said: "The Messenger of Allah (peace and blessings be upon him) has come, the Messenger of Allah (peace and blessings be upon him) has come, the Messenger of Allah (peace and blessings be upon him) has come." I also came to see him. When I looked closely at his face, I realized that this is not the face of a liar. The first hadith that I heard from him was this: "O people! Spread peace (salam) among yourselves, feed the people, maintain the ties of kinship, and pray at night when people are asleep; you will enter Paradise in peace."

It is narrated from Sayyiduna Anas (may Allah be pleased with him), he says that the Messenger of Allah (peace and blessings of Allah be upon him) said: "Among the beautiful names of Allah, there is a name «سلام» which Allah has sent down to the earth, so spread the greeting of peace among yourselves."

It is narrated from Sayyiduna Abdullah (may Allah be pleased with him) that the Noble Prophet (peace and blessings be upon him) said: "Salam is one of the names of Allah, which He has sent down to the earth, so spread it among yourselves. When a person greets people with Salam and they reply to him, then the one who initiated the Salam attains superiority over them, because he reminded them. And if they do not reply, then those (servants of Allah) who are better and purer than them respond to him."

Sayyiduna Hani bin Yazid (may Allah be pleased with him) says: I said, "O Messenger of Allah! Tell me of a deed that will admit me to Paradise." «‏‏‏‏» He (peace and blessings be upon him) said: "Spreading peace widely and speaking good words are such deeds that make forgiveness obligatory."
