Quran 6, Al-An'am (Cattle) ⓘ

6:114Shall I seek other than Allah for judge, when He it is Who hath revealed unto you (this) Scripture, fully explained? Those unto whom We gave the Scripture (aforetime) know that it is revealed from thy Lord in truth. So be not thou (O Muhammad) of the waverers.

أَفَغَيْرَ اللَّهِ أَبْتَغِي حَكَمًا وَهُوَ الَّذِي أَنْزَلَ إِلَيْكُمُ الْكِتَابَ مُفَصَّلًا وَالَّذِينَ آتَيْنَاهُمُ الْكِتَابَ يَعْلَمُونَ أَنَّهُ مُنَزَّلٌ مِنْ رَبِّكَ بِالْحَقِّ فَلَا تَكُونَنَّ مِنَ الْمُمْتَرِينَ

6:115Perfected is the Word of thy Lord in truth and justice. There is naught that can change His words. He is the Hearer, the Knower.

وَتَمَّتْ كَلِمَتُ رَبِّكَ صِدْقًا وَعَدْلًا لَا مُبَدِّلَ لِكَلِمَاتِهِ وَهُوَ السَّمِيعُ الْعَلِيمُ
