The Prophet ﷺ said: The greatest day in Allah's sight is the day of sacrifice and next the day of resting which Isa said on the authority of Thawr is the second day. Five or six sacrificial camels were brought to the Messenger of Allah ﷺ and they began to draw near to see which he would sacrifice first. When they fell down dead, he said something in a low voice, which I could not catch. So I asked: What did he say? He was told that he had said: Anyone who wants can cut off a piece. (Using translation from Abū Dāʾūd 1765)   

قَالَ رَسُولُ اللهِ ﷺ إِنَّ أَعْظَمَ الْأَيَّامِ عِنْدَ اللهِ يَوْمُ النَّحْرِ ثُمَّ يَوْمُ الْقَرِّ وَهُوَ الَّذِي يَلِيهِ قَالَ وَقُدِّمْنَ إِلَى رَسُولِ اللهِ ﷺ بَدَنَاتٌ خَمْسٌ أَوْ سِتٌّ فَطَفِقْنَ يَزْدَلِفْنَ إِلَيْهِ بِأَيَّتِهِنَّ يَبْدَأُ فَلَمَّا وَجَبَتْ جُنُوبُهَا تَكَلَّمَ بِكَلِمَةٍ خَفِيَّةٍ لَمْ أَفْهَمْهَا فَقُلْتُ لِلَّذِي يَلِينِي مَا قَالَ رَسُولُ اللهِ ﷺ؟ قَالَ قَالَ مَنْ شَاءَ اقْتَطَعَ  

[Machine] That he saw Ibn Umar let the water flow, but did not eat anything from the meat of his sacrifice.  

أَنَّهُ رَأَى ابْنَ عُمَرَ أَفَاضَ وَلَمْ يَأْكُلْ مِنْ لَحْمِ نُسُكِهِ شَيْئًا  

[Machine] That he should not eat from it, as mentioned in the verse {So eat from it} [Al-Hajj 28]. This is similar to his saying {And when you have purified yourselves, then hunt} [Al-Ma'idah 2]. So whoever wants can hunt.  

أَنْ لَا يَأْكُلَ مِنْهَا إِنَّمَا قَوْلُهُ تَعَالَى {فَكُلُوا مِنْهَا} [الحج 28] مِثْلُ قَوْلِهِ {وَإِذَا حَلَلْتُمْ فَاصْطَادُوا} [المائدة 2] فَمَنْ شَاءَ اصْطَادَ
