5:48And We revealed to you the Book, with truth, confirming the Scripture that preceded it, and superseding it. So judge between them according to what God revealed, and do not follow their desires if they differ from the truth that has come to you. For each of you We have assigned a law and a method. Had God willed, He could have made you a single nation, but He tests you through what He has given you. So compete in righteousness. To God is your return, all of you; then He will inform you of what you had disputed.

5:49And judge between them according to what God revealed, and do not follow their desires. And beware of them, lest they lure you away from some of what God has revealed to you. But if they turn away, know that God intends to strike them with some of their sins. In fact, a great many people are corrupt.
