Surah Ar-Ra'd, ayah 37

وَكَذَٰلِكَ أَنزَلۡنَٰهُ حُكۡمًا عَرَبِيّٗاۚ وَلَئِنِ ٱتَّبَعۡتَ أَهۡوَآءَهُم بَعۡدَ مَا جَآءَكَ مِنَ ٱلۡعِلۡمِ مَا لَكَ مِنَ ٱللَّهِ مِن وَلِيّٖ وَلَا وَاقٖ ٣٧

Wakadhālika anzalnāhu hukman 'arabiyyan wala'init-taba'ta ahwā'ahum ba'da mā jā'aka minal-'ilmi mā laka minallāhi min waliyyin walā wāq

And thus We have revealed it as an Arabic legislation.⁶⁴³ And if you should follow their inclinations after what has come to you of knowledge, you would not have against Allāh any ally or any protector.
