Hadith Section/Book: Sahih Bukhari Sahih Bukhari Book 82. Punishment of Disbelievers at War with Allah and his Apostle
Narrated By Abu Huraira : The Prophet said, "Seven (people) will be shaded by Allah by His Shade on the Day of Resurrection when there will be no shade except His Shade. (They will be), a just ruler, a young man who has been brought up in the worship of Allah, a man who remembers Allah in seclusion and his eyes are then flooded with tears, a man whose heart is attached to mosques (offers his compulsory congregational prayers in the mosque), two men who love each other for Allah's Sake, a man who is called by a charming lady of noble birth to commit illegal sexual intercourse with her, and he says, 'I am afraid of Allah,' and (finally), a man who gives in charity so secretly that his left hand does not know what his right hand has given."
