Musannaf Ibn Abi Shayba 36:160

Ahmad ibn Abdullah narrated to us, he said: Zuhayr narrated to us, he said: Sulayman al-Taymi narrated to us, that Anas narrated to them, he said: The Messenger of Allah (peace and blessings of Allah be upon him) said: "Who will look at what Abu Jahl has done?" He said: So Ibn Mas'ud set off and found that the two sons of Afra had struck him until he had grown cold. He said: "Are you Abu Jahl?" He took him by his beard. He said: "Is there anything above a man whom you have killed, or a man whom his people have killed?"
