وَكَذَٲلِكَ أَنزَلْنَـٰهُ حُكْمًا عَرَبِيًّاۚ وَلَئِنِ ٱتَّبَعْتَ أَهْوَآءَهُم بَعْدَمَا جَآءَكَ مِنَ ٱلْعِلْمِ مَا لَكَ مِنَ ٱللَّهِ مِن وَلِىٍّ وَلَا وَاقٍ ٣٧
Thus have We revealed it, a decisive utterance in Arabic; and if thou shouldst follow their desires after that which hath come unto thee of knowledge, then truly wouldst thou have from Allah no protecting friend nor defender.
