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 ‏"‏ ‏.‏

It was narrated from Bishr bin Suhaim that: 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. Translation Not Available
