Hazrat Abdur Rahman bin Auf (may Allah be pleased with him) narrated that during the Battle of Badr, I was standing in the row. When I looked to my right and left, I saw that on both my sides were two young boys from the Ansar tribe. I wished that I were between men who were stronger and older than them. One of them gestured towards me and asked, "Uncle! Do you know Abu Jahl?" I said, "Yes! But son, what do you have to do with him?" The boy replied, "I have heard that he abuses the Messenger of Allah (peace and blessings of Allah be upon him). By the One in Whose hand is my soul, if I find him, I will not leave him until one of us who is destined to die first, dies." I was greatly surprised at this. Then the other gestured and said the same things. Only a few moments had passed when I saw Abu Jahl wandering among the people (in the army of the disbelievers). I said to those boys, "The one you were asking me about is there (wandering in front of you)." Both of them drew their swords and rushed at him, and attacked and killed him. After that, they came to the Messenger of Allah (peace and blessings of Allah be upon him) and informed him. The Prophet (peace and blessings of Allah be upon him) asked, "Which of you killed him?" Both youths said, "I killed him." So he asked them, "Have you cleaned your swords?" They replied, "No." Then the Messenger of Allah (peace and blessings of Allah be upon him) looked at both swords and said, "Both of you killed him." And all his belongings will go to Mu'adh bin Amr bin Jamuh. Those two youths were Mu'adh bin 'Afra and Mu'adh bin Amr bin Jamuh.
