Reserve a place under Allah's shade

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),

1. a just ruler,

2. a young man who has been brought up in the worship of Allah,

3. a man who remembers Allah in seclusion and his eyes are then flooded with tears,

4. a man whose heart is attached to mosques (offers his compulsory congregational prayers in the mosque),

5. two men who love each other for Allah's Sake,

6. 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

7. a man who gives in charity so secretly that his left hand does not know what his right hand has given."

(Bukhari:Hadith 798)

PS: it equally applies for muslim women as well.
