حَدَّثَنَا أَحْمَدُ، حَدَّثَنَا ابْنُ وَهْبٍ، عَنْ عَمْرٍو، عَنِ ابْنِ أَبِي هِلاَلٍ، قَالَ وَأَخْبَرَنِي نَافِعٌ، أَنَّ ابْنَ عُمَرَ، أَخْبَرَهُ أَنَّهُ، وَقَفَ عَلَى جَعْفَرٍ يَوْمَئِذٍ وَهْوَ قَتِيلٌ، فَعَدَدْتُ بِهِ خَمْسِينَ بَيْنَ طَعْنَةٍ وَضَرْبَةٍ، لَيْسَ مِنْهَا شَىْءٌ فِي دُبُرِهِ. يَعْنِي فِي ظَهْرِهِ.
