On the authority of Abu Hurairah (, may Allah be pleased with him), who said:
The messenger of Allah prophet Muhammad (peace and blessings of Allah be upon him) said: "There will be seven persons sheltered under the shade of Allah on the day of judgement when there will be no other shade besides his shade. They are: a just ruler: a young man passes his youth in worship and service of Allah - the Lord of honor and glory, one whose heart is perpetually attached to the mosque; two persons who love each other for the sake of Allah, they joined together for his sake and parted for his sake: a man who is invited for sin by a rich beautiful woman but declines, saying I fear Allah. One who gives charity in a secret way without making a show, in a way that his left hand does not know what his right hand spent; and one who remembers Allah in solitude so that his eyes overflow (fill with tear).
(Bukhari and Muslim)
