We have sent down the Book to you with the truth, fulfilling [the predictions] revealed in the previous scriptures and determining what is true therein, and as a guardian over it. Judge, therefore, between them by what God has revealed, and do not follow their vain desires turning away from the truth that has come to you. To every one of you We have ordained a law and a way, and had God so willed, He would have made you all a single community, but He did not so will, in order that He might try you by what He has given you. Vie, then, with one another in doing good works; to God you shall all return; then He will make clear to you about what you have been disputing.
