أَخْبَرَنَا عُبَيْدُ اللَّهِ بْنُ سَعِيدٍ، قَالَ حَدَّثَنَا يَحْيَى، عَنْ سَعْدِ بْنِ إِسْحَاقَ، قَالَ حَدَّثَتْنِي زَيْنَبُ، عَنْ أَبِي سَعِيدٍ الْخُدْرِيِّ، أَنَّ رَسُولَ اللَّهِ صلى الله عليه وسلم نَهَى عَنْ لُحُومِ الأَضَاحِي فَوْقَ ثَلاَثَةِ أَيَّامٍ فَقَدِمَ قَتَادَةُ بْنُ النُّعْمَانِ - وَكَانَ أَخَا أَبِي سَعِيدٍ لأُمِّهِ وَكَانَ بَدْرِيًّا - فَقَدَّمُوا إِلَيْهِ فَقَالَ أَلَيْسَ قَدْ نَهَى عَنْهُ رَسُولُ اللَّهِ صلى الله عليه وسلم قَالَ أَبُو سَعِيدٍ إِنَّهُ قَدْ حَدَثَ فِيهِ أَمْرٌ إِنَّ رَسُولَ اللَّهِ صلى الله عليه وسلم نَهَانَا أَنْ نَأْكُلَهُ فَوْقَ ثَلاَثَةِ أَيَّامٍ ثُمَّ رَخَّصَ لَنَا أَنْ نَأْكُلَهُ وَنَدَّخِرَهُ ‏.‏
