Messenger of Allah ﷺ forbade (people) to cat the flesh of sacrificed animals beyond three days. Abdullah b. Abu Bakr said, I made a mention of that to 'Amra, whereupon she said: He has told the truth, for I heard 'A'isha say: The poor among the people of the desert come (to the towns) on the occasion of Id al-Adha during the lifetime of Messenger of Allah ﷺ. Upon this Messenger of Allah ﷺ said: Retain with you (the flesh) sufficing for three (days), and whatever is left out of that give in charity. After this. they (the Muslims) said: Messenger of Allah, the people make waterskins with the (hides) of their sacrificed animals and they melt fat out of them. Thereupon he said. What the then? They said: You forbade (us) to eat the flesh of sacrificial animals beyond threoq (days), whereupon he said: I forbade you for those (poor persons) who flocked (to the towns on this occasion for getting meat) but now when (this situation has improved) you may eat, preserve and give -in charity.
نَهَى رَسُولُ اللَّهِ ﷺ عَنْ أَكْلِ لُحُومِ الضَّحَايَا بَعْدَ ثَلاَثٍ قَالَ عَبْدُ اللَّهِ بْنُ أَبِي بَكْرٍ فَذَكَرْتُ ذَلِكَ لِعَمْرَةَ فَقَالَتْ صَدَقَ سَمِعْتُ عَائِشَةَ تَقُولُ دَفَّ أَهْلُ أَبْيَاتٍ مِنْ أَهْلِ الْبَادِيَةِ حِضْرَةَ الأَضْحَى زَمَنَ رَسُولِ اللَّهِ ﷺ فَقَالَ رَسُولُ اللَّهِ ﷺ ادَّخِرُوا ثَلاَثًا ثُمَّ تَصَدَّقُوا بِمَا بَقِيَ فَلَمَّا كَانَ بَعْدَ ذَلِكَ قَالُوا يَا رَسُولَ اللَّهِ إِنَّ النَّاسَ يَتَّخِذُونَ الأَسْقِيَةَ مِنْ ضَحَايَاهُمْ وَيَحْمِلُونَ مِنْهَا الْوَدَكَ فَقَالَ رَسُولُ اللَّهِ ﷺ وَمَا ذَاكَ قَالُوا نَهَيْتَ أَنْ تُؤْكَلَ لُحُومُ الضَّحَايَا بَعْدَ ثَلاَثٍ فَقَالَ إِنَّمَا نَهَيْتُكُمْ مِنْ أَجْلِ الدَّافَّةِ الَّتِي دَفَّتْ فَكُلُوا وَادَّخِرُوا وَتَصَدَّقُوا
