Sahih al-Bukhari
Obligatory Charity Tax (Zakat)
Chapter: To give objects of charity with the right hand
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."
