Ar Ra’d Ayah 37

وَكَذَٲلِكَ أَنزَلْنَـٰهُ حُكْمًا عَرَبِيًّا‌ۚ وَلَئِنِ ٱتَّبَعْتَ أَهْوَآءَهُم بَعْدَمَا جَآءَكَ مِنَ ٱلْعِلْمِ مَا لَكَ مِنَ ٱللَّهِ مِن وَلِىٍّ وَلَا وَاقٍ ٣٧ And so We have revealed it as an authority in Arabic. And if you were to follow their desires after ?all? the knowledge that has come to you, there would be none to protect or shield you from Allah.
