Sayyiduna Abu Huraira (may Allah be pleased with him) narrated: A man accepted Islam while he used to eat excessively. When he accepted Islam, he began to eat less. The Messenger of Allah (peace and blessings be upon him) said: "A disbeliever eats with seven intestines, whereas a believer eats with one intestine."
