Salama bin Akwa reported,

The Prophet ﷺ said, "Whoever among you sacrifices an animal should not have any of its meat remaining in his house after three days."When the following year came, the people asked, "Messenger of Allah, shall we do as we did last year?"He replied, "Eat, feed others, and store some away. Last year the people were suffering hardship, so I wanted you to help them through it."

Sahih

عن سلمة بن الأكوع قال

قال النبي ﷺ: من ضحى منكم فلا يصبحن بعد ثالثة وفي بيته منه شيء. فلما كان العام المقبل قالوا: يا رسول الله! نفعل كما فعلنا عام الماضي؟ قال: كلوا وأطعموا وادخروا، فإن ذلك العام كان بالناس جهد فأردت أن تعينوا فيها.
