"I asked Abu Abyub [Al-Ansari] how the slaughtering was done during the time of the Messenger of Allah ﷺ. He said: 'A man would sacrifice a sheep for himself and the people in his household. They would eat from it and feed others, until the people (later) would boast about it and it became as you see now."  

سَمِعْتُ عَطَاءَ بْنَ يَسَارٍ يَقُولُ سَأَلْتُ أَبَا أَيُّوبَ الأَنْصَارِيَّ كَيْفَ كَانَتِ الضَّحَايَا عَلَى عَهْدِ رَسُولِ اللَّهِ ﷺ فَقَالَ كَانَ الرَّجُلُ يُضَحِّي بِالشَّاةِ عَنْهُ وَعَنْ أَهْلِ بَيْتِهِ فَيَأْكُلُونَ وَيُطْعِمُونَ حَتَّى تَبَاهَى النَّاسُ فَصَارَتْ كَمَا تَرَى  

“I asked Abu Ayyub Al- Ansari: ‘How were sacrifices offered among you at the time of the Messenger of Allah ﷺ?’ He said: ‘At the time of the Prophet ﷺ, a man would sacrifice a sheep on behalf of himself and the members of his household, and they would eat some of it and give some to others. Then people started to compete and it because as you see (nowadays).’” (Using translation from Ibn Mājah 3147)   

سَأَلْتُ أَبَا أَيُّوبَ الْأَنْصَارِيَّ صَاحِبَ النَّبِيِّ ﷺ كَيْفَ كَانَتِ الضَّحَايَا فِيكُمْ فِي عَهْدِ رَسُولِ اللهِ ﷺ؟ قَالَ «كَانَ الرَّجُلُ فِي عَهْدِ النَّبِيِّ ﷺ يُضَحِّي بِالشَّاةِ عَنْهُ وَعَنْ أَهْلِ بَيْتِهِ فَيَأْكُلُونَ وَيُطْعِمُونَ مِنْهَا ثُمَّ تَبَاهَى النَّاسُ فَكَانَ كَمَا تَرَى»
