BUKHARI 5393:
from Nāfiʿ —
Ibn ʿUmar never used to take his meal unless a poor man was called to eat with him. One day I brought a poor man to eat with him, the man ate too much, whereupon Ibn ʿUmar said, "O Nafiʿ! Don't let this man enter my house, for I heard the Prophet ﷺ saying, "A believer eats in one intestine (is satisfied with a little food), and a kafir (unbeliever) eats in seven intestines (eats much food).

عن نافع —
كَانَ ابْنُ عُمَرَ لاَ يَأْكُلُ حَتَّى يُؤْتَى بِمِسْكِينٍ يَأْكُلُ مَعَهُ فَأَدْخَلْتُ رَجُلاً يَأْكُلُ مَعَهُ فَأَكَلَ كَثِيرًا فَقَالَ يَا نَافِعُ لاَ تُدْخِلْ هَذَا عَلَىَّ سَمِعْتُ النَّبِيَّ ﷺ يَقُولُ الْمُؤْمِنُ يَأْكُلُ فِي مِعًى وَاحِدٍ وَالْكَافِرُ يَأْكُلُ فِي سَبْعَةِ أَمْعَاءٍ
