Musnad Abu Ya'la al-Mawsili 155:281

Abu Musa narrated to us, Muhammad bin Abdullah al-Ansari narrated to us, Muhammad bin Amr narrated to us, from Abu Salamah, from Abu Hurairah, who said: The Messenger of Allah (ﷺ) said: "The Fire was presented to me, and I saw in it Ibn Qum'ah bin Khandaf, and he was dragging his intestines in the Fire. He was the first to set free the *sa'ibah* (a type of animal dedicated to idols) and change the covenant of Ibrahim. And the person I have seen who most resembles him is Aktham bin al-Jawn." He (the narrator) said: So Aktham said, "O Messenger of Allah, does his resemblance to me harm me?" He said, "No, for you are a Muslim and he is a disbeliever."
