أَفَغَيۡرَ ٱللَّهِ أَبۡتَغِي حَكَمٗا وَهُوَ ٱلَّذِيٓ أَنزَلَ إِلَيۡكُمُ ٱلۡكِتَٰبَ مُفَصَّلٗاۚ وَٱلَّذِينَ ءَاتَيۡنَٰهُمُ ٱلۡكِتَٰبَ يَعۡلَمُونَ أَنَّهُۥ مُنَزَّلٞ مِّن رَّبِّكَ بِٱلۡحَقِّۖ فَلَا تَكُونَنَّ مِنَ ٱلۡمُمۡتَرِينَ

Afaghairal laahi abtaghee hakamanw wa Huwal lazee anzala ilaikumul Kitaaba mufassalaa; wallazeena atai naahumul Kitaaba ya'lamoona annahoo munazzalum mir Rabbika bilhaqqi falaa takoonanna minal mumtareen

Say: "Shall I seek for judge other than Allah? - when He it is Who hath sent unto you the Book, explained in detail." They know full well, to whom We have given the Book, that it hath been sent down from thy Lord in truth. Never be then of those who doubt.
