Musnad Ahmad 1237:3

Yahya ibn Ishaq narrated to us, he said: Ibn Lahi'ah informed us, from Abdullah ibn Hubayrah, from Abu Tamim al-Jayshani, from Abu Basrah al-Ghifari, who said: I came to the Prophet, peace and blessings of Allah be upon him, when I migrated, and that was before I embraced Islam. He milked for me a small sheep that he used to milk for his family, and I drank it. When morning came, I embraced Islam. The family of the Prophet, peace and blessings of Allah be upon him, said: "We spent the night as we spent the previous night, hungry." Then the Messenger of Allah, peace and blessings of Allah be upon him, milked a sheep for me, and I drank it and was satisfied. The Messenger of Allah, peace and blessings of Allah be upon him, said to me: "Are you satisfied?" I said: "O Messenger of Allah, I have become satisfied in a way that I have never been full or satisfied before today." The Prophet, peace and blessings of Allah be upon him, said: "Indeed, the disbeliever eats in seven intestines, and the believer eats in one intestine."
