And had We made the messenger sent to them an angel since they were not convinced by Muhammad, peace and blessings of Allah be upon him, We would surely have made that angel in the form of a human, so that they could hear from him and address him; since it is not in their capability to see the angel in his angelic form, and if the angel came to them in the form of a man the matter would have been confused for them, just as the matter of Muhammad, peace and blessings of Allah be upon him, was confused for them.
