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 أَبُو بَكْرِ بْنُ أَبِي شَيْبَةَ، وَابْنُ، رَافِعٍ قَالاَ حَدَّثَنَا زَيْدُ بْنُ حُبَابٍ، ح وَحَدَّثَنَا إِسْحَاقُ بْنُ إِبْرَاهِيمَ الْحَنْظَلِيُّ، أَخْبَرَنَا عَبْدُ الرَّحْمَنِ بْنُ مَهْدِيٍّ، كِلاَهُمَا عَنْ مُعَاوِيَةَ بْنِ صَالِحٍ، بِهَذَا الإِسْنَادِ ‏.‏
