الطبراني:١٥٦٨٤حَدَّثَنَا عُبَيْدُ بْنُ غَنَّامٍ ثنا أَبُو بَكْرِ بْنُ أَبِي شَيْبَةَ ثنا أَبُو أُسَامَةَ عَنْ سَعِيدِ بْنِ أَبِي عَرُوبَةَ عَنْ قَتَادَةَ عَنْ زُرَارَةَ بْنِ أَوْفَى عَنْ عِمْرَانَ بْنِ حُصَيْنٍ

أَنَّ رَجُلًا عَضَّ يَدَ رَجُلٍ فَانْتَزَعَ يَدَهُ مِنْ فِيهِ فَبَدَرَتْ ثَنِيَّتُهُ «فَأَطَلَّهَا النَّبِيُّ ﷺ» أَوْ قَالَ «فَأَبْطَلَهَا النَّبِيُّ ﷺ»
