Sayyiduna Abdullah bin Amr (may Allah be pleased with them both) said: Seven men came to the Prophet (peace and blessings be upon him), and each of the Companions of the Prophet (peace and blessings be upon him) took one man as a guest, and the Prophet (peace and blessings be upon him) also kept one man with himself. The Messenger of Allah (peace and blessings be upon him) said to him: "What is your name?" He said: Abu Ghazwan. The narrator said: He (peace and blessings be upon him) milked seven goats for him, and he drank the milk of all of them. The Prophet (peace and blessings be upon him) said to him: "Abu Ghazwan, will you accept Islam?" He said: Yes. So he accepted Islam, and the Prophet (peace and blessings be upon him) passed his hand over his chest. When morning came, the Prophet (peace and blessings be upon him) milked only one goat for him, and he could not even finish its milk. He (peace and blessings be upon him) said: "Abu Ghazwan, what is the matter with you?" He said: By the One who sent you as a Prophet, I am full. He (peace and blessings be upon him) said: "Yesterday you had seven intestines, and today you have only one."
