During the lifetime of the Prophet ﷺ we used to take with us the meat of the sacrifices (of Id al Adha) to Medina. (The narrator often said. The meat of the Hadi).  

كُنَّا نَتَزَوَّدُ لُحُومَ الأَضَاحِيِّ عَلَى عَهْدِ النَّبِيِّ ﷺ إِلَى الْمَدِينَةِ وَقَالَ غَيْرَ مَرَّةٍ لُحُومَ الْهَدْىِ  

that once he was not present (at the time of ʿId-al-Adha) and when he came. some meat was presented to him. and the people said (to him), 'This is the meat of our sacrifices" He said. 'Take it away; I shall not taste it. (In his narration) Abu Saʿid added: I got up and went to my brother, Abu Qatada (who was his maternal brother and was one of the warriors of the battle of Badr) and mentioned that to him He Saʿd. 'A new verdict was given in your absence (i.e., meat of sacrifices was allowed to be stored and eaten later on).  

أَنَّهُ كَانَ غَائِبًا فَقَدِمَ فَقُدِّمَ إِلَيْهِ لَحْمٌ قَالَ وَهَذَا مِنْ لَحْمِ ضَحَايَانَا فَقَالَ أَخِّرُوهُ لاَ أَذُوقُهُ قَالَ ثُمَّ قُمْتُ فَخَرَجْتُ حَتَّى آتِيَ أَخِي قَتَادَةَ وَكَانَ أَخَاهُ لأُمِّهِ وَكَانَ بَدْرِيًّا فَذَكَرْتُ ذَلِكَ لَهُ فَقَالَ إِنَّهُ قَدْ حَدَثَ بَعْدَكَ أَمْرٌ  

The Prophet ﷺ said, "Whoever has slaughtered a sacrifice should not keep anything of Its meat after three days." When it was the next year the people said, "O Messenger of Allah ﷺ! Shall we do as we did last year?" He said, ' Eat of it and feed of it to others and store of it for in that year the people were having a hard time and I wanted you to help (the needy).  

قَالَ النَّبِيُّ ﷺ مَنْ ضَحَّى مِنْكُمْ فَلاَ يُصْبِحَنَّ بَعْدَ ثَالِثَةٍ وَفِي بَيْتِهِ مِنْهُ شَىْءٌ فَلَمَّا كَانَ الْعَامُ الْمُقْبِلُ قَالُوا يَا رَسُولَ اللَّهِ نَفْعَلُ كَمَا فَعَلْنَا عَامَ الْمَاضِي قَالَ كُلُوا وَأَطْعِمُوا وَادَّخِرُوا فَإِنَّ ذَلِكَ الْعَامَ كَانَ بِالنَّاسِ جَهْدٌ فَأَرَدْتُ أَنْ تُعِينُوا فِيهَا  

We used to salt some of the meat of sacrifice and present it to the Prophet ﷺ at Medina. Once he said, "Do not eat (of that meat) for more than three days." That was not a final order, but (that year) he wanted us to feed of it to others, Allah knows better.  

قَالَتِ الضَّحِيَّةُ كُنَّا نُمَلِّحُ مِنْهُ فَنَقْدَمُ بِهِ إِلَى النَّبِيِّ ﷺ بِالْمَدِينَةِ فَقَالَ لاَ تَأْكُلُوا إِلاَّ ثَلاَثَةَ أَيَّامٍ وَلَيْسَتْ بِعَزِيمَةٍ وَلَكِنْ أَرَادَ أَنْ يُطْعِمَ مِنْهُ وَاللَّهُ أَعْلَمُ  

the freed slave of Ibn Azhar that he witnessed the Day of ʿId-al-Adha with ʿUmar bin Al-Khattab. ʿUmar offered the ʿId prayer before the sermon and then delivered the sermon before the people, saying, "O people! Messenger of Allah ﷺ has forbidden you to fast (on the first day of) each of these two 'Ida, for one of them is the Day of breaking your fast, and the other is the one, on which you eat the meat of your sacrifices."  

يَا أَيُّهَا النَّاسُ إِنَّ رَسُولَ اللَّهِ ﷺ قَدْ نَهَاكُمْ عَنْ صِيَامِ هَذَيْنِ الْعِيدَيْنِ أَمَّا أَحَدُهُمَا فَيَوْمُ فِطْرِكُمْ مِنْ صِيَامِكُمْ وَأَمَّا الآخَرُ فَيَوْمٌ تَأْكُلُونَ نُسُكَكُمْ  

(in continuation of above). Then I witnessed the ʿId with ʿUthman bin ʿAffan, and that was on a Friday. He offered the prayer before the sermon, saying, "O people! Today you have two 'Its (festivals) together, so whoever of those who live at Al-ʿAwali (suburbs) would like to wait for the Jumua prayer, he may wait, and whoever would like to return (home) Is granted my permission to do so."  

يَا أَيُّهَا النَّاسُ إِنَّ هَذَا يَوْمٌ قَدِ اجْتَمَعَ لَكُمْ فِيهِ عِيدَانِ فَمَنْ أَحَبَّ أَنْ يَنْتَظِرَ الْجُمُعَةَ مِنْ أَهْلِ الْعَوَالِي فَلْيَنْتَظِرْ وَمَنْ أَحَبَّ أَنْ يَرْجِعَ فَقَدْ أَذِنْتُ لَهُ  

(in continuation of above). Then I witnessed (the 'Its) with ʿAli bin Abi Talib, and he too offered the ʿId prayer before the sermon and then delivered the sermon before the people and said, "Messenger of Allah ﷺ has forbidden you to eat the meat of your sacrifices for more than three days."  

إِنَّ رَسُولَ اللَّهِ ﷺ نَهَاكُمْ أَنْ تَأْكُلُوا لُحُومَ نُسُكِكُمْ فَوْقَ ثَلاَثٍ وَعَنْ مَعْمَرٍ عَنِ الزُّهْرِيِّ عَنْ أَبِي عُبَيْدٍ نَحْوَهُ  

ʿAbdullah bin ʿUmar said, "Messenger of Allah ﷺ said, "Eat of the meat of sacrifices (of ʿId al Adha) for three days." When ʿAbdullah departed from Mina, he used to eat (bread with) oil, lest he should eat of the meat of Hadi (which is regarded as unlawful after the three days of the ʿId).  

قَالَ رَسُولُ اللَّهِ ﷺ كُلُوا مِنَ الأَضَاحِيِّ ثَلاَثًا وَكَانَ عَبْدُ اللَّهِ يَأْكُلُ بِالزَّيْتِ حِينَ يَنْفِرُ مِنْ مِنًى مِنْ أَجْلِ لُحُومِ الْهَدْىِ
