And to thee we have sent down the Book of the Koran with truth, confirmatory of previous Scriptures, and their safeguard. Judge therefore between them by what God hath sent down, and follow not their desires by deserting the truth which hath come unto thee. To every one of you have we given a rule and a beaten track. And if God had pleased He had surely made you all one people; but He would test you by what He hath given to each. Be emulous, then, in good deeds. To God shall ye all return, and He will tell you concerning the subjects of your disputes.
