Then We revealed the Book to you (O Muhammad!) with Truth, confirming whatever of the Book was revealed before, and protecting and guarding over it. Judge, then, in the affairs of men in accordance with the Law that Allah has revealed, and do not follow their desires in disregard of the Truth which has come to you. For each of you We have appointed a Law and a way of life. And had Allah so willed, He would surely have made you one single community; instead, (He gave each of you a Law and a way of life) in order to test you by what He gave you. Vie, then, one with another in good works. Unto Allah is the return of all of you; and He will then make you understand the truth concerning the matters on which you disagreed.
