The Messenger of Allah ﷺ delivered a sermon on the days of Tashriq (11th, 12th, and 13th of Dhul-Hijjah) and said: “No one will enter Paradise but a Muslim soul, and these days are the days of eating and drinking.” (Using translation from Ibn Mājah 1720)
أَنَّ مُنَادِيَ رَسُولِ اللهِ ﷺ خَرَجَ فِي أَيَّامِ التَّشْرِيقِ فَقَالَ «إِنَّهُ لَا يَدْخُلُ الْجَنَّةَ إِلَّا نَفْسٌ مُسْلِمَةٌ أَلَا وَإِنَّ هَذِهِ الْأَيَّامَ أَكْلٌ وَشُرْبٌ»
