Ady bin Thabit al-Ansari عدي بن ثابت الأنصاري الكوفي · The Book of ad-Dahaya (Sacrifices)

"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.""

"The Messenger of Allah forbade keeping the meat of the sacrificial animals for more than three days, then he said: 'Eat and feed other,"' (Sahih )
