Abdul-Rahman bin Awf reported,

While I was standing in the ranks on the day of Badr, I looked to my right and my left, and there I was between two young boys from the Ansar, both still young in age. I had wished I were between two stronger men. Then one of them nudged me and asked, "Uncle, do you know Abu Jahl?"I said, "Yes. What do you want with him, my nephew?"He said, "I have been told that he insults the Messenger of Allah ﷺ. By the One in whose hand my soul is, if I see him, my body will not part from his until the one of us whose time has come dies first."I was amazed at this. Then the other boy nudged me and said the same thing.It was not long before I caught sight of Abu Jahl moving about among the people. I said, "Do you not see? There is the man you were asking about."They both rushed at him and struck him with their swords until they killed him. Then they returned to the Messenger of Allah ﷺ and told him what happened.He asked, "Which of you killed him?"Each one of them said, "I killed him."He asked, "Have you wiped your swords clean?"They replied, "No."He examined the two swords and said, "Both of you killed him." He awarded his spoils to Muaz bin Amr bin Jamuh.The two men were Muaz bin Amr bin Jamuh and Muaz bin Afra.

عن عبد الرحمن بن عوف أنه قال

بينا أنا واقف في الصف يوم بدر، نظرت عن يميني وشمالي، فإذا أنا بين غلامين من الأنصار، حديثة أسنانهما، تمنيت لو كنت بين أضلع منهما، فغمزني أحدهما، فقال: يا عم هل تعرف أبا جهل؟ قال: قلت نعم، وما حاجتك إليه يا ابن أخي؟ قال: أخبرت أنه يسب رسول الله ﷺ، والذي نفسي بيده لئن رأيته لا يفارق سوادي سواده حتى يموت الأعجل منا، قال: فتعجبت لذلك، فغمزني الآخر، فقال مثلها: قال: فلم أنشب أن نظرت إلى أبي جهل يزول في الناس، فقلت: ألا تريان؟ هذا صاحبكما الذي تسألان عنه، قال: فابتدراه فضرباه بسيفيهما، حتى قتلاه، ثم انصرفا إلى رسول الله ﷺ فأخبراه فقال: أيكما قتله؟ فقال كل واحد منهما: أنا قتلت، فقال: هل مستحما سيفيكما؟ قالا: لا، فنظر في السيفين فقال: كلاكما قتله وقضى بسلبه لمعاذ بن عمرو بن الجموح (والرجلان: معاذ بن عمرو بن الجموح ومعاذ بن عفراء)
