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.  

قَالَ رَسُولُ اللَّهِ ﷺ مَنْ يَنْظُرُ لَنَا مَا صَنَعَ أَبُو جَهْلٍ فَانْطَلَقَ ابْنُ مَسْعُودٍ فَوَجَدَهُ قَدْ ضَرَبَهُ ابْنَا عَفْرَاءَ حَتَّى بَرَكَ قَالَ فَأَخَذَ بِلِحْيَتِهِ فَقَالَ آنْتَ أَبُو جَهْلٍ فَقَالَ وَهَلْ فَوْقَ رَجُلٍ قَتَلْتُمُوهُ أَوْ قَالَ قَتَلَهُ قَوْمُهُ قَالَ وَقَالَ أَبُو مِجْلَزٍ قَالَ أَبُو جَهْلٍ فَلَوْ غَيْرُ أَكَّارٍ قَتَلَنِي  

A similar tradition has been transmitted by a different chain of narrators, on the same authority with a slight difference In the wording.  

قَالَ رَسُولُ اللَّهِ ﷺ مَنْ يَعْلَمُ لِي مَا فَعَلَ أَبُو جَهْلٍ بِمِثْلِ حَدِيثِ ابْنِ عُلَيَّةَ وَقَوْلِ أَبِي مِجْلَزٍ كَمَا ذَكَرَهُ إِسْمَاعِيلُ
