The Messenger of Allah ﷺ said, "The believer eats with one stomach, while the disbeliever eats with seven."
أن رسول الله ﷺ قال: المؤمن يأكل في معى واحد، والكافر يأكل في سبعة أمعاء.
Muslim narrated it in the Book of Drinks (2061) from Muhammad bin Muthanna, who said, Abdul-Rahman narrated to us, from Sufyan, from Abu Zubayr, from Jabir and Ibn Umar, who mentioned it.
