A man passed by the Messenger of Allaah (Sal Allaahu Alaihi wa Sallam) while he was sitting with others, and said “As-salaamu ‘alaykum.” The Prophet (Sal Allaahu Alaihi wa Sallam) said, “[He will have] ten hasanaat.”Another man passed by and said “As-Salaamu Alaikum wa Rahmatullaah (peace be upon you and the mercy of Allaah).” The Prophet (Sal Allaahu Alaihi wa Sallam) said, “[He will have] twenty hasanaat.” Another man passed by and said “As-Salaamu Alaikum wa Rahmatullaahi wa Barakaatuh (peace be upon you and the mercy of Allaah and His blessings).” The Prophet (Sal Allaahu Alaihi wa Sallam) said, “[He will have] thirty hasanaat.”
Once a man asked the Prophet (Sal Allaahu Alaihi wa Sallam) about which aspect of Islam was best. The Prophet (Sal Allaahu Alaihi wa Sallam) replied: “Feeding the hungry, and saying salaam to those you know and those you don’t know.” (Bukhaari and Muslim)
3. “As-Salaamu Alaikum” is a means of entering Jannah
The Prophet (Sal Allaahu Alaihi wa Sallam)said: “You will not enter Paradise until you believe, and you will not believe until you love one another. Shall I not tell you about something which, if you do it, you will love one another? Spread salaam (the greeting of peace) among you.” (Muslim)
4. “As-Salaamu Alaikum” gets rid of sins
The Prophet (Sal Allaahu Alaihi wa Sallam) also said,“When two Muslims meet (give salaam), and shake hands, they are forgiven their sins before they part (with each other).” (Abu Dawud)
5. “As-Salaamu Alaikum” is the greeting of the people of Jannah
“Then, those that feared their Lord shall be driven in companies into Paradise. When they draw near its gates will be opened, and its keepers will say to them: “Salaamun ‘Alaikum” (Peace be upon you), you have done well. Enter and live in it for ever.”(Surah Zumar 39:73)
6. Even Allaah says “As-Salaamu Alaikum”
Allah sends His Salaam upon the people who believe in Him, especially the prophets such as Nuh, Ibraheem, Ismaeel, Musa, etc. (Surah as-Saaffaat) as well as other pious people.
Jibreel came to house of the Prophet (sal Allahu alayhi wa sallam) and Khadeeja (may Allah be pleased with her) was there. Jibreel said: “Allah sends his salaam to Khadeeja.” The Prophet (sal Allahu alayhi wa sallam) said: “O Khadeeja, Allah is sending His salaams to you.” She (may Allah be pleased with her)said, “Allah is As-Salaam. And upon you O Jibreel, be as-salaam and upon you Rasulullah be as-salaam.” [Bukhaari]
It is obligatory to return the greeting of“As-Salaamu Alaikum”
“The Muslim has five rights over his fellow-Muslim: he should return his salaams, visit him when he is sick, attend his funeral, accept his invitation, and pray for mercy for him [say “Yar ha'mu kallaah”] when he sneezes.”(Bukhaari, Muslim)
We should say “As-Salaamu Alaikum” when we enter our homes
“When you enter houses, greet (with peace) one another with a salutation from Allah, blessed and good. As such Allah makes clear to you His verses so that you understand.”(Surah an-Nur: 61)
“As-Salaamu Alaikum”is also to be said at time of leaving
The Prophet (Sal Allaahu Alaihi wa Sallam) said:“When one of you joins a gathering, he should greet those present; and when he leaves them he should salute them, because the first salutation is not better than the last one.” (Abu Dawud and Tirmithi)
Why would you want to give up something beautiful for something ugly?
It is sad to see that when it comes to the matters of Dunya, we strive our utmost to give our families and friends the best. Yet when it comes to greetings, we forget the most beautiful and comprehensive greeting “As-Salaamu Alaikum”, which is also a prayer….a prayer of peace and blessing….of security and protection from all harm and all evil…..a blessing that Allaah Himself sends down to His beloved slaves……a greeting of the people of Jannah itself.
