the Messenger of Alllah forbade (Eating) the meat of sacrificial animals after three days. Then Qatadh bin An-Nu' man, who was brother of Abu Sa'eed through his mo0ther, and had been present at Badr, came and they offered him (some of the meat) .He said: "Didn't the Messenger of Allah forbid it?" Abu Sa eed said: "Something happened later. The Messenger of Allah forbade us to eat it for more than three days, then he allowed us to eat it and store it." (Sahih ) (Using translation from Nasāʾī 4428)
أَنَّ رَسُولَ اللهِ ﷺ «نَهَى عَنْ لُحُومِ الْأَضَاحِيِّ فَوْقَ ثَلَاثَةِ أَيَّامٍ» فَقَدِمَ قَتَادَةُ بْنُ النُّعْمَانِ وَكَانَ أَخًا أَبِي سَعِيدٍ لِأُمِّهِ وَكَانَ بَدْرِيًّا فَقَدِمُوا إِلَيْهِ فَقَالَ أَلَيْسَ قَدْ نَهَى عَنْهُ رَسُولُ اللهِ ﷺ قَالَ أَبُو سَعِيدٍ إِنَّهُ حَدَثَ فِيهِ أَمْرٌ إِنَّ رَسُولَ اللهِ ﷺ «نَهَى أَنْ نَأْكُلَهُ فَوْقَ ثَلَاثَةِ أَيَّامٍ ثُمَّ رَخَّصَ لَنَا أَنْ نَأْكُلَهُ وَنَدَّخِرَهُ»
