Musannaf Ibn Abi Shayba 3:5167

Abu Khalid narrated to us, from Ibn ‘Ajlan, from Zayd ibn Aslam, who said: The Messenger of Allah (peace and blessings of Allah be upon him) said: "O Allah, do not make my grave an idol that is prayed to. The wrath of Allah has intensified against a people who took the graves of their prophets as places of worship."
