Anas (May Allah be pleased with him) reported: Messenger of Allah (PBUH) said, "Three follow a dead body: members of his family, his possessions and his deeds. Two of them return and one remains with him. His family and his possessions return; his deeds remain with him".
[Al-Bukhari and Muslim].

Commentary: This Hadith induces one to perform such deeds which always remain with him in the grave, where every being and thing leaves one and he is all alone in the grave. What is left is his good deeds which become the means of refuge and salvation.
