Musnad Abu Ya'la al-Mawsili 139:5

Zuhayr narrated to us, Jarir narrated to us, from Sulayman al-Taymi, from Anas ibn Malik, who said: The Messenger of Allah (ﷺ) said: "Who will look to see what Abu Jahl has done?" So Abdullah ibn Mas'ud set out and found that the two sons of Afra had struck him until he had grown cold. He said: "O enemy of Allah, are you Abu Jahl?" He replied: "Is there anything above a man whom his people have killed—or whom you have killed?"
