Abu Huraira reported: The Prophet, peace and blessings be upon him, said, “There are seven whom Allah will shade on a day when there is no shade but His. They are a just ruler, a youth who grew up in the worship of Allah, one whose heart is attached to the mosques, two who love each other, meet each other, and depart from each other for the sake of Allah, a man who is tempted by a beautiful woman of high status but he rejects her, saying , ‘I fear Allah,’ and one who spends in charity and hides it such that his right hand does not know what his left hand has given, and one who remembered Allah in private and he wept.”
