Sahih Muslim | Book 22 | Hadith Number 4856

Narrated by Abdullah b. Waqid
Abdullah b. Waqid reported: Allah's Messenger (may peace be upon him) forbade (people) to cat the flesh of sacrificed animals beyond three days. Abdullah b. Abu Bakr said, I made a mention of that to 'Amra, whereupon she said: He has told the truth, for I heard 'Aisha say: The poor among the people of the desert come (to the towns) on the occasion of Id al-Adha during the lifetime of Allah's Messenger (may peace be upon him). Upon this Allah's Messenger (may peace be upon him) said: Retain with you (the flesh) sufficing for three (days), and whatever is left out of that give in charity. After this, they (the Muslims) said: Allah's Messenger, the people make water-skins with the (hides) of their sacrificed animals and they melt fat out of them. Thereupon he said. What the then? They said: You forbade (us) to eat the flesh of sacrificial animals beyond three (days), whereupon he said: I forbade you for those (poor persons) who flocked (to the towns on this occasion for getting meat) but now when (this situation has improved) you may eat, preserve and give -in charity.
