Musnad Abi Ya'la 7346 — from his father (Muhammad bin Amr bin Hazm)

Abu Bakr bin Muhammad bin Amr bin Hazm (may Allah have mercy on him) narrates from his father (Muhammad bin Amr bin Hazm (may Allah have mercy on him)) that Sayyiduna Amr bin Hazm (may Allah be pleased with him) went to Sayyiduna Amr bin al-As (may Allah be pleased with him) and said that Sayyiduna Ammar (may Allah be pleased with him) had been martyred, whereas the Messenger of Allah (peace and blessings be upon him) had said: "A rebellious group will kill him." Then Sayyiduna Amr bin al-As (may Allah be pleased with him) went to Sayyiduna Mu'awiyah (may Allah be pleased with him) and said that Sayyiduna Ammar (may Allah be pleased with him) had been martyred. Sayyiduna Mu'awiyah (may Allah be pleased with him) said: "Ammar has been killed, so what of it?" Sayyiduna Amr bin al-As (may Allah be pleased with him) said: I heard the Messenger of Allah (peace and blessings be upon him) say: "A rebellious group will kill him." At this Sayyiduna Mu'awiyah (may Allah be pleased with him) said (to Sayyiduna Amr bin al-As (may Allah be pleased with him)): "You are caught in your own slip! Did we kill him? He was killed only by Sayyiduna Ali (may Allah be pleased with him) and his companions (who brought him into the battle)."
