أَخْبَرَنَا يُوسُفُ بْنُ عِيسَى، قَالَ حَدَّثَنَا الْفَضْلُ بْنُ مُوسَى، قَالَ حَدَّثَنَا يَزِيدُ، - وَهُوَ ابْنُ زِيَادِ بْنِ أَبِي الْجَعْدِ - عَنْ عَبْدِ الرَّحْمَنِ بْنِ عَابِسٍ، عَنْ أَبِيهِ، قَالَ سَأَلْتُ عَائِشَةَ عَنْ لُحُومِ الأَضَاحِي، قَالَتْ كُنَّا نَخْبَأُ الْكُرَاعَ لِرَسُولِ اللَّهِ صلى الله عليه وسلم شَهْرًا ثُمَّ يَأْكُلُهُ ‏.‏
