the Messenger of Allah forbade eating the meat of sacrificial animals after three days" (Sahih ) (Using translation from Nasāʾī 4423)  

أَنَّ رَسُولَ اللهِ ﷺ «نَهَى أَنْ تُؤْكَلَ لُحُومُ الْأَضَاحِيِّ بَعْدَ ثَلَاثٍ»  

Then I saw ʿAli bin Abi Talib ؓ after that on the day of Eid; he started with the prayer before the khutbah and he prayed with no adhan or iqamah. Then he said: I heard the Messenger of Allah ﷺ forbidding (the people) to leave any of the meat of their sacrifice after three days. (Using translation from Aḥmad 587)  

سَمِعْتُ رَسُولَ اللهِ ﷺ «يَنْهَى أَنْ يُمْسِكَ أَحَدٌ مِنْ نُسُكِهِ شَيْئًا فَوْقَ ثَلَاثَةِ أَيَّامٍ»  

"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»
