(Quran: Fully Detailed*)
Shall I seek other than God as a source of law, when He has revealed to you this book fully detailed? Those who received the scripture recognize that it has been revealed from your Lord, truthfully. You shall not harbor any doubt.
أَفَغَيرَ اللَّهِ أَبتَغى حَكَمًا وَهُوَ الَّذى أَنزَلَ إِلَيكُمُ الكِتٰبَ مُفَصَّلًا وَالَّذينَ ءاتَينٰهُمُ الكِتٰبَ يَعلَمونَ أَنَّهُ مُنَزَّلٌ مِن رَبِّكَ بِالحَقِّ فَلا تَكونَنَّ مِنَ المُمتَرينَ
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
*6:113-115 Upholding any source beside the Quran reflects disbelief in the Quran (Appendix 18).
