حَدَّثَنَا أَبُو بَكْرِ بْنُ أَبِي شَيْبَةَ، حَدَّثَنَا يَزِيدُ بْنُ هَارُونَ، أَنْبَأَنَا دَاوُدُ بْنُ أَبِي هِنْدٍ، عَنِ الشَّعْبِيِّ، عَنْ مُحَمَّدِ بْنِ صَفْوَانَ، أَنَّهُ مَرَّ عَلَى النَّبِيِّ ـ صلى الله عليه وسلم ـ بِأَرْنَبَيْنِ مُعَلِّقَهُمَا فَقَالَ يَا رَسُولَ اللَّهِ إِنِّي أَصَبْتُ هَذَيْنِ الأَرْنَبَيْنِ فَلَمْ أَجِدْ حَدِيدَةً أُذَكِّيهِمَا بِهَا فَذَكَّيْتُهُمَا بِمَرْوَةٍ أَفَآكُلُ قَالَ " كُلْ " .
