It is narrated from Sayyiduna Abu Huraira, may Allah be pleased with him, that a disbeliever (Jahjah bin Sa'id Ghafari) came to the Messenger of Allah, peace and blessings be upon him, as a guest. The Prophet, peace be upon him, ordered a goat to be milked, and he drank all of it. Then another goat was milked, and he drank that as well. Then he drank the milk of a third goat, until he drank the milk of seven goats. The next morning, that person became a Muslim. The Prophet, peace be upon him, gave him goat's milk to drink, and he drank it. Then he was given to drink a second time, but he could not drink it. Then the Prophet, peace be upon him, said: "A believer drinks in one intestine, and a disbeliever drinks in seven intestines."
