Nabeesha reported,
The Messenger of Allah ﷺ said, "We had previously forbidden you from eating the meat of sacrificial animals beyond three days so that there would be enough for everyone. Now Allah has brought abundance, so eat, store it away, and trade with it. Indeed, these days are days of eating, drinking, and remembrance of Allah." 
Abu Dawud 2813
Sahihحدثنا مسدد حدثنا يزيد بن زريع حدثنا خالد الحذاء عن أبي المليح
عن نبيشة قال
قال رسول الله ﷺ إنا كنا نهيناكم عن لحومها أن تأكلوها فوق ثلاث لكي تسعكم فقد جاء الله بالسعة فكلوا وادخروا واتجروا ألا وإن هذه الأيام أيام أكل وشرب وذكر الله عز وجل
