"The day of Arafat and the day of sacrifice and the day of At-Tashriq are our Id, the people of Islam, and they are days of eating and drinking."  

أَنَّ رَسُولَ اللَّهِ ﷺ قَالَ إِنَّ يَوْمَ عَرَفَةَ وَيَوْمَ النَّحْرِ وَأَيَّامَ التَّشْرِيقِ عِيدُنَا أَهْلَ الإِسْلاَمِ وَهِيَ أَيَّامُ أَكْلٍ وَشُرْبٍ
