the Messenger of Allah forbade eating the meat of the sacrificial animals after three days then he said: "Eat, take some with you (if traveling). And store some." ( Sahih) (Using translation from Nasāʾī 4426)
أَنَّ رَسُولَ اللهِ ﷺ نَهَى عَنْ أَكْلِ لُحُومِ الْأَضَاحِيِّ بَعْدَ ثَلَاثٍ ثُمَّ قَالَ بَعْدَ ذَلِكَ كُلُوا وَتَزَوَّدُوا وَادَّخِرُوا
