أَخْبَرَنَا قُتَيْبَةُ، وَمُحَمَّدُ بْنُ عَبْدِ اللَّهِ بْنِ يَزِيدَ، قَالاَ حَدَّثَنَا سُفْيَانُ، عَنْ هِشَامِ بْنِ عُرْوَةَ، عَنْ فَاطِمَةَ، عَنْ أَسْمَاءَ، قَالَتْ نَحَرْنَا فَرَسًا عَلَى عَهْدِ رَسُولِ اللَّهِ صلى الله عليه وسلم فَأَكَلْنَاهُ . وَقَالَ قُتَيْبَةُ فِي حَدِيثِهِ فَأَكَلْنَا لَحْمَهُ . خَالَفَهُ عَبْدَةُ بْنُ سُلَيْمَانَ .
