Imam Baihaqi narrates in discontinuation from Ibne Abbas, that As-Salaam is amongst Allah’s names and also this is the greeting of the dwellers of Paradise.
Imaam Bukhari in his Al-Adabul-Mufrad narrates from Hazrat Anas RA that the Holy Prophet
said, "As-salaam is indeed a name from the names of Allah, which Allah has placed upon the Earth, therefore spread salaam amongst yourselves in abundance."
It has been narrated from Hadhrat Ali RA that the Holy Prophet
"Commonly in Islam there are six rights of a Muslim upon a Muslim: when he meets him he should give him salaam; when he invites him (to a meal) he should accept it; when he sneezes he should bless him; when he falls ill he should visit him; when he dies he should accompany his funeral and he should prefer for him that which he prefers for himself." The Virtue of Commencing Salaam
It has been narrated by Abu Umamah RA that the Holy Prophet
said, "Whoever commences Salaam is very close to Allah and His Messenger Muhammad ()" Ibn Sunni has narrated this.
In Imaam Ahmad’s narration there is, "The closest to Allah, the most glorious and eminent one, from amongst all the people is the one who commences salaam."
Similarly Tabrani narrates from Abu Darda RA, who says that we asked the Holy Prophet
, "O Prophet of Allah, we meet each other, so who from amongst us should give salaam first?" The Holy Prophet
replied, "The one who is the most obedient to Allah from amongst you." Reward For Giving Salaam
It has been narrated by Saalim that the Holy Prophet
said, "He who says Assalaamu Alaikum (Peace be upon you) ten rewards are written down for him, and he who says Assalaamu Alaikum wa rahmatullah (Peace be upon you and Allah’s mercy) for him twenty rewards are written down and he who says Assalaamu Alaikum wa rahmatullahi wa barakatuh (Peace be upon you and Allah’s mercy and blessing) thirty rewards are written down (for him)."
In support of this Hadith we find a narration by Ibn Umar in Musannaf-Abdul-Razzak; It has been narrated in this Hadith that a person came in the presence of the Holy Prophet
and said, "Assalamu Alaikum." The Holy Prophet
replied, "Ten." Then a second Sahabi came and said, "Assalamu Alaikum wa rahmatullah." The Holy Prophet replied, "Twenty." Then a third Sahabi arrived and said, "Assalamu Alaikum wa rahmatullahi wa barakatuh." Upon this the Holy Prophetsaid, "Thirty." That is to say upon three words thirty rewards will be written down.
