صَحِيحُ مُسْلِمٍ
Sahih Muslim 1970 a
The Book of Sacrifices
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.
وَحَدَّثَنَا قُتَيْبَةُ بْنُ سَعِيدٍ، حَدَّثَنَا لَيْثٌ، ح وَحَدَّثَنِي مُحَمَّدُ بْنُ رُمْحٍ، أَخْبَرَنَا اللَّيْثُ، عَنْ نَافِعٍ، عَنِ ابْنِ عُمَرَ، عَنِ النَّبِيِّ صلى الله عليه وسلم أَنَّهُ قَالَ لاَ يَأْكُلْ أَحَدٌ مِنْ لَحْمِ أُضْحِيَّتِهِ فَوْقَ ثَلاَثَةِ أَيَّامٍ .
Ibn 'Umar reported Allah's Messenger (ﷺ) having said: None of you should eat the flesh of his sacrificial animal beyond three days.
