Ar-Ra'd 13:37

وَكَذَٰلِكَ أَنزَلْنَٰهُ حُكْمًا عَرَبِيًّۭا ۚ وَلَئِنِ ٱتَّبَعْتَ أَهْوَآءَهُم بَعْدَمَا جَآءَكَ مِنَ ٱلْعِلْمِ مَا لَكَ مِنَ ٱللَّهِ مِن وَلِىٍّۢ وَلَا وَاقٍۢ

Thus have We revealed it to be a judgment of authority in Arabic. Wert thou to follow their (vain) desires after the knowledge which hath reached thee, then wouldst thou find neither protector nor defender against Allah.
