25) باب الأَرْنَبِ
أَخْبَرَنَا قُتَيْبَةُ، قَالَ حَدَّثَنَا حَفْصٌ، عَنْ عَاصِمٍ، وَدَاوُدَ، عَنِ الشَّعْبِيِّ، عَنِ ابْنِ صَفْوَانَ، قَالَ أَصَبْتُ أَرْنَبَيْنِ فَلَمْ أَجِدْ مَا أُذَكِّيهِمَا بِهِ فَذَكَّيْتُهُمَا بِمَرْوَةٍ فَسَأَلْتُ النَّبِيَّ صلى الله عليه وسلم عَنْ ذَلِكَ فَأَمَرَنِي بِأَكْلِهِمَا .
