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)
خَطَبَنَا رَسُولُ اللهِ ﷺ أَيَّامَ التَّشْرِيقِ فَقَالَ «لَا يَدْخُلُ الْجَنَّةَ إِلَّا مُؤْمِنٌ وَإِنَّ هَذِهِ الْأَيَّامَ أَيَّامُ أَكْلٍ وَشُرْبٍ»
