And when Jesus son of Mary said: O Children of Israel! Lo! I am the messenger of Allah unto you, confirming that which was (revealed) before me in the Torah, and bringing good tidings of a messenger who cometh after me, whose name is the Praised One. Yet when he hath come unto them with clear proofs, they say: This is mere magic.
