Do they say that the Prophet has fabricated it himself? O Prophet, tell them: “If I have fabricated it myself, then there is nothing that you can do to protect me from the wrath of Allah. He knows fully well what you say about it. Enough is He as a witness between me and you. He is the Oft-Forgiving, the Most Merciful.”
