He led us in prayer before delivering the sermon and then addressed the people saying: Messenger of Allah ﷺ has forbidden you to eat the flesh of your sacrificial animals beyond three nights, so do not eat that.
فَصَلَّى لَنَا قَبْلَ الْخُطْبَةِ ثُمَّ خَطَبَ النَّاسَ فَقَالَ إِنَّ رَسُولَ اللَّهِ ﷺ قَدْ نَهَاكُمْ أَنْ تَأْكُلُوا لُحُومَ نُسُكِكُمْ فَوْقَ ثَلاَثِ لَيَالٍ فَلاَ تَأْكُلُوا
"The Messenger of Allah has forbidden you from eating the meat of your sacrificaial animals for more than three day." (Sahih )
إِنَّ رَسُولَ اللَّهِ ﷺ قَدْ نَهَاكُمْ أَنْ تَأْكُلُوا لُحُومَ نُسُكِكُمْ فَوْقَ ثَلاَثٍ
Then I was present with ‘Ali. He prayed before delivering the khutbah, with no adhan or iqamah, then he delivered the khutbah. He said: O people, the Messenger of Allah ﷺ forbade eating from your sacrificial animals after three days, so do not eat from them after today.
ثُمَّ شَهِدْتُهُ مَعَ عَلِيٍّ فَصَلَّى قَبْلَ أَنْ يَخْطُبَ بِلا أَذَانٍ وَلا إِقَامَةٍ ثُمَّ خَطَبَ فَقَالَ يَا أَيُّهَا النَّاسُ إِنَّ رَسُولَ اللهِ ﷺ قَدْ نَهَى أَنْ تَأْكُلُوا نُسُكَكُمْ بَعْدَ ثَلاثِ لَيَالٍ فَلا تَأْكُلُوهَا بَعْدُ
"The Messenger of Allah has forbidden you from eating the meat of your sacrificaial animals for more than three day." (Sahih ) (Using translation from Nasāʾī 4425)
إِنَّ رَسُولَ اللهِ ﷺ قَدْ «نَهَاكُمْ أَنْ تَأْكُلُوا لُحُومَ نُسُكِكُمْ فَوْقَ ثَلَاثِ لَيَالٍ»
