The Prophet [SAW] commanded him to call out on the days of At-Tashriq that no one would enter Paradise except a believer, and that these were the days of eating and drinking. (Using translation from Nasāʾī 4994)   

أن رَسُولَ اللَّهِ ﷺ أَمَرَهُ أَوْ أَمَرَ رَجُلًا يُنَادِي أَيَّامَ التَّشْرِيقِ «أَنَّهُ لَا يَدْخُلُ الْجَنَّةَ إِلَّا مُؤْمِنٌ وَهِيَ أَيَّامُ أَكْلٍ وَشُرْبٍ»  

[Machine] Umru, break your fast, "for these are the days that the Messenger of Allah ﷺ used to order us to break our fast and forbid us from fasting." So Abdullah broke his fast, and I ate with him.  

عَمْرٌو أَفْطِرْ «فَإِنَّ هَذِهِ الْأَيَّامَ الَّتِي كَانَ رَسُولُ اللَّهِ ﷺ يَأْمُرُنَا بِفِطْرِهَا وَيَنْهَانَا عَنْ صِيَامِهَا» فَأَفْطَرَ عَبْدُ اللَّهِ فَأَكَلَ وَأَكَلْتُ مَعَهُ
