What Reward Man Gets After Death

Abu Hurayrah رضي الله عنه reported the Messenger of Allaah صلى الله عليه و سلم  as saying: 

"When a man dies, his acts come to an end, but three, recurring charity, or knowledge (by which people) benefit, or a pious son, who prays for him (for the deceased)."

Muslim Book 13 No. 4005
