Narrated Abu Huraira:

The Prophet (p.b.u.h) said, "Seven people will be shaded by Allah under His shade on the day when there will be no shade except His. They are:

(1) a just ruler;

(2) a young man who has been brought up in the worship of Allah, (i.e. worship Allah (Alone) sincerely from his childhood),

(3) a man whose heart is attached to the mosque (who offers the five compulsory congregational prayers in the mosque);

(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 an illegal sexual intercourse with her and says: I am afraid of Allah;

(6) a person who practices charity 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) a person who remembers Allah in seclusion and his eyes get flooded with tears."
