Narrated Abu Huraira:

The Prophet said, “Allah will give shade, to seven, on the Day when there will be no shade but His. (These seven persons are)

1. a just ruler,
2. a youth who has been brought up in the worship of Allah (i.e. worships Allah sincerely from childhood),
3. a man whose heart is attached to the mosques (i.e. to pray the compulsory prayers in the mosque in congregation),
4. two persons who love each other only for Allah’s sake and they meet and part in Allah’s cause only,
5. a man who refuses the call of a charming woman of noble birth for illicit intercourse with her and says: I am afraid of Allah,
6. a man who gives charitable gifts so secretly that his left hand does not know what his right hand has given (i.e. nobody knows how much he has given in charity),
7. and a person who remembers Allah in seclusion and his eyes are then flooded with tears.”

Here is a high quality recording of Surah Ar-Rahman by Sh Mishary Rashid Al Efasy. Inshallah I plan on adding the whole quran once I can make sure there are no copyrights on the recordings.

According to Imam Nawawl, greeting with the words of as-Salam-u-‘Alaikum is a Sunnah, and responding to it is Wajib (obligatory), but this essentiality is of the nature of Kifaya, meaning thereby that if a few persons out of the whole assembly or group respond to the greeting it will absolve all of the responsibility of response but if no response comes forth from any quarter all are held responsible for it.

Abu Huraira reported Allah’s Messenger (may peace be upon him) as saying: The rider should first greet the pedestrian, and the pedestrian the one who is seated and a small group should greet a larger group (with as-Salam-u-‘Alaikum).

Abu Huraira reported Allah’s Messenger (may peace be upon him) as saying: Six are the rights of a Muslim over another Muslim. It was said to him: Allah’s Messenger, what are these? Thereupon he said: When you meet him, offer him greetings;when he invites you to a feast accept it. when he seeks your council give him, and when he sneezes and says:” All praise is due to Allah,” you say Yarhamuk Allah (may Allah show mercy to you) ; and when he fails ill visit him; and when he dies follow his bier.
