They are being told that this is the Word of Allah, as if to say, "Our Prophet has not fabricated the Qur'an but We have bestowed this on him, and if We take it back from him, the Prophet has no power to invent such a thing nor has any other man the power to help the Prophet to present such a miraculous Book.
