The Prophet ﷺ said: The day of Arafah, the day of sacrifice, the days of tashriq are (the days of) our festival, O people of Islam. These are the days of eating and drinking. (Using translation from Abū Dāʾūd 2419)
قَالَ رَسُولُ اللَّهِ ﷺ «يَوْمُ عَرَفَةَ وَأَيَّامُ التَّشْرِيقِ عِيدُنَا أَهْلَ الْإِسْلَامِ وَهِيَ أَيَّامُ أَكْلٍ وَشُرْبٍ»
