Mishkat al-Masabih 4028
‘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 God's Messenger. 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 God’s Messenger 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.” God’s Messenger 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.

عَنْ عَبْدِ الرَّحْمَنِ بْنِ عَوْفٍ قَالَ: إِنِّي وَاقِفٌ فِي الصَّفِّ يَوْمَ بَدْرٍ فَنَظَرْتُ عَنْ يَمِينِي وَعَنْ شِمَالِي فَإِذَا بِغُلَامَيْنِ مِنَ الْأَنْصَارِ حَدِيثَة أسنانها فتمنيت أَنْ أَكُونَ بَيْنَ أَضْلَعَ مِنْهُمَا فَغَمَزَنِي أَحَدُهُمَا فَقَالَ: يَا عَمِّ هَلْ تَعْرِفُ أَبَا جَهْلٍ؟ قُلْتُ: نَعَمْ فَمَا حَاجَتُكَ إِلَيْهِ يَا ابْنَ أَخِي؟ قَالَ: أُخْبِرْتُ أَنَّهُ يَسُبُّ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ وَالَّذِي نَفْسِي بِيَدِهِ لَئِنْ رَأَيْتُهُ لَا يُفَارِقُ سَوَادِي سَوَادَهُ حَتَّى يَمُوتَ الْأَعْجَلُ مِنَّا فَتَعَجَّبْتُ لِذَلِكَ قَالَ: وَغَمَزَنِي الْآخَرُ فَقَالَ لِي مِثْلَهَا فَلَمْ أَنْشَبْ أَنْ نَظَرْتُ إِلَى أَبِي جَهْلٍ يَجُولُ فِي النَّاسِ فَقُلْتُ: أَلَا تَرَيَانِ؟ هَذَا صَاحِبُكُمَا الَّذِي تَسْأَلَانِي عَنْهُ قَالَ: فابتدراه بسيفهما فَضَرَبَاهُ حَتَّى قَتَلَاهُ ثُمَّ انْصَرَفَا إِلَى رَسُولِ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ فأخبراهُ فَقَالَ: «أَيُّكُمَا قَتَلَهُ؟» فَقَالَ كُلُّ وَاحِدٍ مِنْهُمَا: أَنَا قَتله فَقَالَ: «هلْ مسحتُما سيفَيكما؟» فَقَالَا: لَا فَنَظَرَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ إِلَى السَّيْفَيْنِ فَقَالَ: «كِلَاكُمَا قَتَلَهُ» . وَقَضَى رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ بِسَلَبِهِ لِمُعَاذِ بن عَمْرِو بن الْجَمُوحِ وَالرَّجُلَانِ: مُعَاذُ بْنُ عَمْرِو بْنِ الْجَمُوحِ ومعاذ بن عفراء
