عَنْ عَبْدِ اللَّهِ بْنِ بُرَيْدَةَ عَنْ أَبِيهِ رَضِيَ اللَّهُ عَنْهُ قَالَ قَالَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَآلِهِ وَسَلَّمَ نَهَيْتُكُمْ عَنْ أَكْلِ لُحُومِ الْأَضَاحِيِّ بَعْدَ ثَلَاثٍ فَكُلُوا وَتَزَوَّدُوا وَادَّخِرُوا
It is narrated from Sayyiduna Buraidah (may Allah be pleased with him) that the Messenger of Allah (peace and blessings be upon him) said: I had forbidden you from eating the meat of sacrificial animals for more than three days, but now I command you to eat it, take it as provision for the journey, and store it.
