‘Abdar-Rahman b. ‘Auf said

When I stood in the rank at the battle of Badr I looked to my right and my left, and when I saw that I was between two young men of the Ansar I wished that I had been between men who were stronger than they. One of them pinched me and said, "Do you know Abu Jahl, uncle?" and I replied, "Yes, but what do you want with him, nephew?” He said, “I have been told that he reviles Allah's Messenger ﷺ. By Him in whose hand my soul is, if I see him I shall not leave him till the one of us who is to die first dies.” I was astonished at that, and then the other pinched me and said the same to me. Before long I saw Abu Jahl going round among the people and I said, “Look, this is the man about whom you were asking.” They then hastened to him with their swords and struck him till they killed him, after which they went to Allah's Messenger ﷺ and informed him. He asked which of them had killed him and they both claimed to have done so. He then asked if they had wiped their swords, and when they replied that they had not he looked at the swords and said, “Both of you killed him.” Allah's Messenger ﷺ then decided that what was taken from him should go to Mu'adh b. ‘Amr b. al-Jamuh. The two men were Mu'adh b. ‘Amr b. al-Jamah and Mu'adh b. ‘Afra’.* *’Afra’ was his mother. His father was al-Harith. (Bukhari and Muslim.)
