البيهقي:١٩٢١٥أَخْبَرَنَا أَبُو الْحَسَنِ عَلِيُّ بْنُ أَحْمَدَ بْنِ عَبْدَانَ أنبأ أَحْمَدُ بْنُ عُبَيْدٍ الصَّفَّارُ ثنا ابْنُ مِلْحَانَ ثنا يَحْيَى بْنُ بُكَيْرٍ ثنا لَيْثٌ هُوَ ابْنُ سَعْدٍ عَنْ يَحْيَى بْنِ سَعِيدٍ عَنِ الْقَاسِمِ بْنِ مُحَمَّدٍ عَنِ ابْنِ خَبَّابٍ أَنَّ أَبَا سَعِيدِ بْنَ مَالِكٍ الْخُدْرِيَّ قَدِمَ مِنْ سَفَرٍ فَقُدِّمَ إِلَيْهِ مِنْ لُحُومِ الْأَضَاحِيِّ فَقَالَ مَا أَنَا بِآكِلِهِ حَتَّى أَسْأَلَ فَانْطَلَقَ إِلَى أَخِيهِ لِأُمِّهِ وَكَانَ بَدْرِيًّا قَتَادَةَ بْنِ النُّعْمَانِ فَسَأَلَهُ عَنْ ذَلِكَ فَقَالَ

bukhari:3997ʿAbdullāh b. Yūsuf > al-Layth > Yaḥyá b. Saʿīd > al-Qāsim b. Muḥammad > Ibn Khabbāb from my father

Abu Saʿid bin Malik Al-Khudri returned from a journey and his family offered him some meat of sacrifices offered at ʿId 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 ﷺ cancelling the prohibition of eating sacrifices after three days."  

البخاري:٣٩٩٧حَدَّثَنَا عَبْدُ اللَّهِ بْنُ يُوسُفَ حَدَّثَنَا اللَّيْثُ قَالَ حَدَّثَنِي يَحْيَى بْنُ سَعِيدٍ عَنِ الْقَاسِمِ بْنِ مُحَمَّدٍ عَنِ ابْنِ خَبَّابٍ أَنَّ أَبَا سَعِيدِ بْنِ مَالِكٍ الْخُدْرِيَّ ؓ 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
