باب بَيَانِ مَا كَانَ مِنَ النَّهْىِ عَنْ أَكْلِ لُحُومِ الأَضَاحِيِّ بَعْدَ ثَلاَثٍ فِي أَوَّلِ الإِسْلاَمِ وَبَيَانِ نَسْخِهِ وَإِبَاحَتِهِ إِلَى مَتَى شَاءَ
Sahih Muslim 1972 d

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).
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 ‏.‏
