Hadith 702
Sayyiduna Ubayy bin Ka'b (may Allah be pleased with him) narrates: The Prophet Muhammad (peace and blessings be upon him) said: "The example of the world can be given through what the son of Adam eats; whatever comes out of the body of the son of Adam. Even though he puts spices and salt in it, you should consider what it becomes (after staying in a person's stomach)."
