The Book of Drinks (Kitab Al-Ashriba)

Muslim :: Book 23 : Hadith 5115

Nafi' reported that Ibn 'Umar saw a poor man. He placed food before him and he ate much. He (Ibn 'Umar) said: He should not come to me. for I heard Allah's Messenger (may peace be upon him) as saying that the non-Muslim eats in seven intestines.
