The Book of Sacrifices
35/5. Chapter:
The prohibition of eating sacrificial meat for more than three days, which applied at the beginning of Islam but was then abrogated, and now it is permissible to eat it as long as one wants.
Sahih Muslim
حَدَّثَنَا يَحْيَى بْنُ يَحْيَى، قَالَ قَرَأْتُ عَلَى مَالِكٍ عَنْ أَبِي الزُّبَيْرِ، عَنْ جَابِرٍ، عَنِ النَّبِيِّ صلى الله عليه وسلم أَنَّهُ نَهَى عَنْ أَكْلِ لُحُومِ الضَّحَايَا بَعْدَ ثَلاَثٍ ثُمَّ قَالَ بَعْدُ " كُلُوا وَتَزَوَّدُوا وَادَّخِرُوا " .
Jabir reported that Allah's Apostle (ﷺ) forbade eating of the flesh of sacrificed animals beyond three (days). but afterwards said: Eat, make a provision, and keep it.
