And We have sent down the Book to you with truth, confirming and conserving the previous Books. So judge between them by what Allah has sent down and do not follow their whims and desires deviating from the Truth that has come to you. We have appointed a law and a practice for every one of you. Had Allah willed, He would have made you a single community, but He wanted to test you regarding what has come to you. So compete with each other in doing good. Every one of you will return to Allah and He will inform you regarding the things about which you differed.
