أَخْبَرَنَا عَمْرُو بْنُ عَلِيٍّ، قَالَ حَدَّثَنَا يَحْيَى، قَالَ حَدَّثَنَا سُفْيَانُ، قَالَ حَدَّثَنَا أَبُو إِسْحَاقَ، عَنْ عَمْرِو بْنِ غَالِبٍ، قَالَ قَالَتْ عَائِشَةُ أَمَا عَلِمْتَ أَنَّ رَسُولَ اللَّهِ صلى الله عليه وسلم قَالَ " لاَ يَحِلُّ دَمُ امْرِئٍ مُسْلِمٍ إِلاَّ رَجُلٌ زَنَى بَعْدَ إِحْصَانِهِ أَوْ كَفَرَ بَعْدَ إِسْلاَمِهِ أَوِ النَّفْسُ بِالنَّفْسِ " . وَقَّفَهُ زُهَيْرٌ .
