Sahih Bukhari Volume 5, Book 64, Hadith 3999

حَدَّثَنَا عَبْدُ اللَّهِ بْنُ يُوسُفَ، حَدَّثَنَا اللَّيْثُ، قَالَ حَدَّثَنِي يَحْيَى بْنُ سَعِيدٍ، عَنِ الْقَاسِمِ بْنِ مُحَمَّدٍ، عَنِ ابْنِ خَبَّابٍ، أَنَّ أَبَا سَعِيدِ بْنِ مَالِكٍ الْخُدْرِيَّ ـ رضى الله عنه ـ قَدِمَ مِنْ سَفَرٍ، فَقَدَّمَ إِلَيْهِ أَهْلُهُ لَحْمًا مِنْ لُحُومِ الأَضْحَى فَقَالَ مَا أَنَا بِآكِلِهِ حَتَّى أَسْأَلَ، فَانْطَلَقَ إِلَى أَخِيهِ لأُمِّهِ وَكَانَ بَدْرِيًّا قَتَادَةَ بْنِ النُّعْمَانِ فَسَأَلَهُ، فَقَالَ إِنَّهُ حَدَثَ بَعْدَكَ أَمْرٌ نَقْضٌ لِمَا كَانُوا يُنْهَوْنَ عَنْهُ مِنْ أَكْلِ لُحُومِ الأَضْحَى بَعْدَ ثَلاَثَةِ أَيَّامٍ

Narrated By Ibn Khabbab : Abu Said bin Malik Al-Khudri returned from a journey and his family offered him some meat of sacrifices offered at 'Id-ul-Adha. On that he said, "I will not eat it before asking (whether it is allowed)." He went to his maternal brother, Qatada bin N i 'man, who was one of the Badr warriors, and asked him about it. Qatada said, "After your departure, an order was issued by the Prophet cancelling the prohibition of eating sacrifices after three days."
