حَدَّثَنَا هَنَّادٌ، حَدَّثَنَا أَبُو الأَحْوَصِ، عَنْ سُفْيَانَ، عَنْ أَبِي إِسْحَاقَ، عَنْ عَاصِمِ بْنِ ضَمْرَةَ، قَالَ قَالَ عَلِيٌّ رضى الله عنه فِي الْخَطَإِ أَرْبَاعًا خَمْسٌ وَعِشْرُونَ حِقَّةً وَخَمْسٌ وَعِشْرُونَ جَذَعَةً وَخَمْسٌ وَعِشْرُونَ بَنَاتِ لَبُونٍ وَخَمْسٌ وَعِشْرُونَ بَنَاتِ مَخَاضٍ ‏.‏
