حَدَّثَنَا ابْنُ الْمُثَنَّى، وَابْنُ، بَشَّارٍ قَالاَ حَدَّثَنَا مُؤَمَّلُ بْنُ إِسْمَاعِيلَ، حَدَّثَنَا حَمَّادُ بْنُ زَيْدٍ، عَنِ ابْنِ عَوْنٍ، قَالَ لَوْ عَلِمْنَا أَنَّ كَلِمَةَ، الْحَسَنِ تَبْلُغُ مَا بَلَغَتْ لَكَتَبْنَا بِرُجُوعِهِ كِتَابًا وَأَشْهَدْنَا عَلَيْهِ شُهُودًا وَلَكِنَّا قُلْنَا كَلِمَةٌ خَرَجَتْ لاَ تُحْمَلُ .
