We have also sent down unto thee the book of the Koran with truth, confirming that scripture which was revealed before it; and preserving the same safe from corruption. Judge therefore between them according to that which God hath revealed; and follow not their desires, by swerving from the truth which hath come unto thee. Unto every of you have we given a law, and an open path; and if God had pleased, he had surely made you one people; but he hath thought fit to give you different laws, that he might try you in that which he hath given you respectively. Therefore strive to excel each other in good works: Unto God shall ye all return, and then will he declare unto you that concerning which ye have disagreed.
