It is narrated from Urwah bin al-Zubayr that on the day of the Battle of the Trench, from among the disbelievers of Quraysh, of Banu Amir bin Lu'ayy and then of Banu Malik bin Hisl, Amr bin Abd Wadd bin Nasr bin Malik bin Hisl was killed by Sayyiduna Ali bin Abi Talib (may Allah be pleased with him). Imam al-Hakim says: I have mentioned, regarding the killing of Amr bin Abd Wadd, what reached me from the hadith with chains (musnad) and from the Maghazi of Urwah bin al-Zubayr, Musa bin Uqbah and Muhammad bin Ishaq bin Yasar, so that it may be established before the fair-minded among the people of knowledge that Amr bin Abd Wadd was killed only by the Commander of the Believers Ali bin Abi Talib (may Allah be pleased with him), and that no one else shared in killing him. What prompted me to such a thorough investigation of this matter was the statement of a Kharijite who claimed that Muhammad bin Maslamah also struck him a blow and took some of his belongings. By Allah! This has not reached us from any Companion or Successor. And how could this be correct, when the statement of Sayyiduna Ali (may Allah be pleased with him) has reached us in which he said: "I held myself above taking the belongings of my cousin, so I left them," and this was his reply to the Commander of the Believers Umar bin al-Khattab (may Allah be pleased with him) in the presence of the Messenger of Allah (peace and blessings be upon him).
