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
أَخْبَرَنَا قُتَيْبَةُ، قَالَ حَدَّثَنَا حَمَّادٌ، عَنْ عَمْرٍو، عَنْ نَافِعِ بْنِ جُبَيْرِ بْنِ مُطْعِمٍ، عَنْ بِشْرِ بْنِ سُحَيْمٍ، أَنَّ النَّبِيَّ صلى الله عليه وسلم أَمَرَهُ أَنْ يُنَادِيَ أَيَّامَ التَّشْرِيقِ ‏
"‏ أَنَّهُ لاَ يَدْخُلُ الْجَنَّةَ إِلاَّ مُؤْمِنٌ وَهِيَ أَيَّامُ أَكْلٍ وَشُرْبٍ ‏"‏ ‏.‏
