O people of Medina, do not eat the flesh of sacrificed animals beyond three days. Ibn al-Muthanni said: Three days. They (the Companions of the Holy Prophet) complained to the Messenger of Allah (may peace he upon him) that they had children and servants of theirs (to feed), whereupon he said: Eat, and feed others, and store, and make it a provision of food. (Using translation from Muslim 1973)
قَالَ رَسُولُ ﷺ يَا أَهْلَ الْمَدِينَةِ لَا تَأْكُلُوا لُحُومَ الْأَضَاحِيِّ فَوْقَ ثَلَاثَةِ أَيَّامٍ فَشَكَوْا إِلَى رَسُولِ اللهِ ﷺ أَنَّ لَهُمْ عِيَالًا وَحَشَمًا وَخَدَمًا فَقَالَ كُلُوا وَأَطْعِمُوا وَاحْبِسُوا وَادَّخِرُوا
