Abdullah bin Mubarak عبد الله بن المبارك · The Book of ad-Dahaya (Sacrifices)

"I saw 'Ali bin Abi Talib - may Allah honor his face on the day of 'Id. He started with the prayer before the Khutbah, and then he prayed with no Adhan and no Iqamah. Then he said: 'I heard the Messenger of Allah forbidding anyone form keeping anything of his sacrificial animal for more than three days." (Sahih )

"I asked 'Aishah about the meat of the sacrificial animals and she said: 'We used to keep the trotters for the Messenger of Allah for a month, then he would eat them.""
