Maliks Muwatta Book 16, Hadith Number 32.
Section : Burying the Dead.
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.”
