It is narrated from Hazrat Abu Huraira (may Allah be pleased with him) that once a guest came to the Prophet Muhammad (peace and blessings be upon him) who was a disbeliever. At the order of the Prophet (peace and blessings be upon him), milk from a goat was milked for him and he drank all of it. The Prophet (peace and blessings be upon him) ordered milk from a second goat, and he drank that as well. In this way, he drank the milk of seven goats. The next day, he accepted Islam. At the order of the Prophet (peace and blessings be upon him), milk from a goat was milked for him and he drank it. When the Prophet (peace and blessings be upon him) ordered milk from a second goat, he could not finish it. Upon this, the Prophet (peace and blessings be upon him) said: "A Muslim drinks in one intestine, and a disbeliever drinks in seven intestines."
