Nafi' b. 'Ujayr b. 'Abd Yazid b. Hashim · Food, Meals

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).

Once Ibn Umar was taking his supper while he was listening to the recitation of (Quran by) the Imam (in the Isha prayer).
