Abu Dawud bin Abi Salih relates: One day Marwan came and saw a man who had placed his face on the blessed grave of the Prophet (peace and blessings be upon him). He said: "Do you know what you are doing?" The man turned towards Marwan, and it was Sayyiduna Abu Ayyub al-Ansari (may Allah be pleased with him). He said: "Yes! I have come to the Messenger of Allah; I have not come to a stone."
This narration will appear in full in the Book of the Caliphate.
Imam Ahmad recorded this. Regarding Dawud bin Abi Salih, Imam al-Dhahabi said: No one other than al-Walid bin Kathir narrated from him. However, Kathir bin Zayd also narrated from him, as mentioned in the Musnad, and no one has declared him weak.
