أَفَغَيرَ اللَّهِ أَبتَغي حَكَمًا وَهُوَ الَّذي أَنزَلَ إِلَيكُمُ الكِتابَ مُفَصَّلًا ۚ وَالَّذينَ آتَيناهُمُ الكِتابَ يَعلَمونَ أَنَّهُ مُنَزَّلٌ مِن رَبِّكَ بِالحَقِّ ۖ فَلا تَكونَنَّ مِنَ المُمتَرينَ

[Say], "Then is it other than Allah I should seek as judge while it is He who has revealed to you the Book explained in detail?" And those to whom We [previously] gave the Scripture know that it is sent down from your Lord in truth, so never be among the doubters.
