Sahih al-Bukhari · Book 70: Food, Meals · A believer eats in one intestine
Narrated `Amr:
حَدَّثَنَا عَلِيُّ بْنُ عَبْدِ اللَّهِ ، حَدَّثَنَا سُفْيَانُ ، عَنْ عَمْرٍو ، قَالَ كَانَ أَبُو نَهِيكٍ رَجُلاً أَكُولاً فَقَالَ لَهُ ابْنُ عُمَرَ إِنَّ رَسُولَ اللَّهِ صلى الله عليه وسلم قَالَ " إِنَّ الْكَافِرَ يَأْكُلُ فِي سَبْعَةِ أَمْعَاءٍ ". فَقَالَ فَأَنَا أُومِنُ بِاللَّهِ وَرَسُولِهِ .
Abu Nahik was avaricious eater. Ibn `Umar said to him, "Allah's Messenger (ﷺ) said, "A Kafir (unbeliever) eats in seven intestines (eats much)." On that Abu Nahik said, "But I believe in Allah and His Apostle ."
