Chapter : The murder of Abu Jahl.

It has been narrated on the authority of Anas b. Malik that the Messenger of Allah (may peace be upon him) said (after the encounter at Badr): Who will ascertain for us what has happened to Abu Jahl? Ibn Mas’ud went (to gather this information). He found that the two sons of ‘Afra’ had struck him and he lay cold at the point of death. He caught him by his beard and said: Art thou Abu Jahl? He said: is there anybody superior to the person you have killed, or (he said) his people have killed him. Ibn Mas’ud says that, according to Abu Mijlaz, Abu Jahl said: Alas! a person other than a farmer would have killed me.
