It is narrated from Sayyiduna Duhak bin Sufyan Kilabi (may Allah be pleased with him) that the Messenger of Allah (peace and blessings be upon him) said to him: "Duhak! What is your food?" He replied: "O Messenger of Allah! Milk and meat." The Prophet (peace and blessings be upon him) then asked: "In the end, what does it become when it leaves the body?" He replied: "You know best, O Messenger." The Prophet (peace and blessings be upon him) said: "Indeed, Allah Almighty has set forth as an example for the world that which comes out from the son of Adam."
