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، حَدَّثَنَا سُفْيَانُ بْنُ عُيَيْنَةَ، عَنْ عَمْرٍو، عَنْ عَطَاءٍ، عَنْ جَابِرٍ، قَالَ كُنَّا نَتَزَوَّدُهَا إِلَى الْمَدِينَةِ عَلَى عَهْدِ رَسُولِ اللَّهِ صلى الله عليه وسلم .
Jabir reported: We made provision (out of the flesh of sacrificed animals for our journey) to Medina during the lifetime of Allah's Messenger (ﷺ).
