أَخْبَرَنَا رِزْقُ اللَّهِ بْنُ مُوسَى، قَالَ حَدَّثَنَا سُفْيَانُ، عَنْ أَيُّوبَ بْنِ مُوسَى، عَنِ الزُّهْرِيِّ، عَنْ عُرْوَةَ، عَنْ عَائِشَةَ، قَالَتْ أُتِيَ النَّبِيُّ صلى الله عليه وسلم بِسَارِقٍ فَقَطَعَهُ قَالُوا مَا كُنَّا نُرِيدُ أَنْ يَبْلُغَ مِنْهُ هَذَا . قَالَ " لَوْ كَانَتْ فَاطِمَةَ لَقَطَعْتُهَا " .
