721 - Isma'il ibn al-Fadl informed me, saying: I heard Abu Umayyah Muhammad ibn Ibrahim say: I heard in a circle where Ahmad ibn Hanbal, Yahya ibn Ma'in, Abu Khaythamah, and al-Mu'ayti were present; they mentioned: "'Ammar will be killed by the rebellious group," and they said: "There is no authentic hadith regarding it."
