Quran 18:5 Al-Kahf, ayah 5 of 110

مَّا لَهُم بِهِۦ مِنْ عِلْمٍ وَلَا لِـَٔابَآئِهِمْ ۚ كَبُرَتْ كَلِمَةً تَخْرُجُ مِنْ أَفْوَٰهِهِمْ ۚ إِن يَقُولُونَ إِلَّا كَذِبًا ۝٥

18:5 (A thing) whereof they have no knowledge, nor (had) their fathers, Dreadful is the word that cometh out of their mouths. They speak naught but a lie.
