Muhammad bin Umarah bin Khuzaymah bin Thabit narrates: My grandfather kept holding back his weapons (that is, he took no part in the fighting) until Sayyiduna Ammar (may Allah be pleased with him) was martyred at Siffin; then my grandfather drew his sword and fought until he was martyred. He said: I heard the Messenger of Allah (peace and blessings be upon him) say: "The rebellious group will kill him."
Ahmad and al-Tabarani recorded it; its chain contains Abu Ma'shar, who is weak (layyin).
