Ar-Ra'd - 13:37

وَكَذَلِكَ أَنزَلْنَاهُ حُكْمًا عَرَبِيًّا وَلَئِنِ اتَّبَعْتَ أَهْوَاءهُم بَعْدَ مَا جَاءكَ مِنَ الْعِلْمِ مَا لَكَ مِنَ اللّهِ مِن وَلِيٍّ وَلاَ وَاقٍ
[13:37]
And thus have We revealed it, a true judgment in Arabic, and if you follow their low desires after what has come to you of knowledge, you shall not have against Allah any guardian or a protector.
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.
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.
