Yahya related to me from Malik from Yahya ibn Said from Wafid ibn Amr ibn Said ibn Muadh from Nafi ibn Jubayr ibn Mutim from Masud ibn al-Hakam from AIi ibn Abi Talib that the Messenger of Allah, may Allah bless him and grant him peace, used to stand up when a funeral procession passed by, and then sit down again afterwards.
Muwatta Malik Book 16, Hadith 34
← Previous Hadith Yahya related to me from Malik from Hisham ibn Urwa that his father said, "I would not want to be buried in al-Baqi. I would prefer to be buried elsewhere. The one who is buried in al-Baqi is one of two people. Either he is unjust (dhalim), and I would not like to be buried with him, or he is salih, and I would not like his bones to be disturbed for me."

Muwatta Malik Book 16, Hadith 33 Next Hadith → ahya related to me from Malik that he had heard that AIi ibn Abi Talib used to rest his head on graves and lie on them.

Malik said, "As far as we can see ,it is only forbidden to sit on graves to relieve oneself."
