Chapter 70: Food, Meals
Narrated Nafi ': Ibn 'Umar 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 'Umar said, "O Nafi '!
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).
