Verse 37

وَكَذَٰلِكَ أَنزَلْنَـٰهُ حُكْمًا عَرَبِيًّا وَلَئِنِ ٱتَّبَعْتَ أَهْوَآءَهُم بَعْدَ مَا جَآءَكَ مِنَ ٱلْعِلْمِ مَا لَكَ مِنَ ٱللَّهِ مِن وَلِىٍّ وَلَا وَاقٍ

And We thus revealed to you wisdom in Arabic. And if you ever obey their wishes despite the knowledge that you have received, you will have no one besides God as an ally or a guardian.
