Hadith on Death: After death, only his deeds remain

Anas ibn Malik reported: The Messenger of Allah, peace and blessings be upon him, said, “Three things follow a deceased person. Two of them return and one remains. His family, his wealth, and his deeds follow him. His family and wealth return, but his deeds remain.”
