Al-Ma'idah 5:48 وانزلنا اليك الكتاب بالحق مصدقا لما بين يديه من الكتاب ومهيمنا عليه فاحكم بينهم بما انزل الله ولا تتبع اهواءهم عما جاءك من الحق لكل جعلنا منكم شرعة ومنهاجا ولو شاء الله لجعلكم امة واحدة ولاكن ليبلوكم في ما اتاكم فاستبقوا الخيرات الى الله مرجعكم جميعا فينبيكم بما كنتم فيه تختلفون ٤٨

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.
