Say-O Messenger-to these polytheists: "Is it other than Allah my God and your God I seek as a judge between me and you, while He Glorified be He is the One who sent down to you the Qur'an clarifying therein the judgment in what you differ therein of my matter and your matter?" and the Children of Israel whom Allah gave the Torah and the Gospel know with a certain knowledge that this Qur'an is sent down upon you-O Messenger-from your Lord with the truth, so do not be among the doubters in anything of what We revealed to you.
