Volume: 007 / Book Number: 068 / Hadith Number: 477
Narrated 'Aisha:
We used to salt some of the meat of sacrifice and present it to the Prophet at Medina. Once he said, "Do not eat (of that meat) for more than three days." That was not a final order, but (that year) he wanted us to feed of it to others, Allah knows better.
