The Prophet said: “There are
seven whom Allah will shade in His Shade on the Day when there is no shade
except His Shade:

1. A just ruler;
2. A youth who grew up in the worship of Allah,the Mighty and Majestic;
3. A man whose heart is attached to the mosques;
4. two men who love each other for Allah’s sake, meeting for that and parting
upon that;
5. A man who is called by a woman of beauty and position [for illegal
intercourse], but be says: ‘I fear Allah’,
6. A man who gives in charity and hides it, such that his left hand does not know what his right hand gives in charity; and
7. A man who remembered Allah in private and so his
eyes shed tears.”
