5.48 . And unto thee have We revealed the Scripture with the truth , confirming whatever Scripture was before it , and a watcher over it . So judge between them by that which Allah hath revealed , and follow not their desires away from the truth which hath come unto thee . For each We have appointed a divine law and a traced out way . Had Allah willed He could have made you one community . But that He may try you by that which He hath given you ( He hath made you as ye are ) . So vie one with another in good works . Unto Allah ye will all return , and He will then inform you of that wherein ye differ .
