Mishkat al-Masabih, hadith 2528

وَعَن جابرٍ قَالَ: كُنَّا لَا نَأْكُلُ مِنْ لُحُومِ بُدْنِنَا فَوْقَ ثَلَاثٍ فَرَخَّصَ لَنَا رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ فَقَالَ: «كُلُوا وَتَزَوَّدُوا» . فَأَكَلْنَا وتزودنا

Jabir said they were not accustomed to eat the flesh of their sacrificial camels for more than three days, but God’s messenger gave them licence saying, “Eat and preserve the meat,” so they did so. Bukhari and Muslim.
