مَّا لَهُم بِهِۦ مِنْ عِلْمٍۢ وَلَا لِءَابَآئِهِمْ ۚ كَبُرَتْ كَلِمَةًۭ تَخْرُجُ مِنْ أَفْوَٰهِهِمْ ۚ إِن يَقُولُونَ إِلَّا كَذِبًۭا
(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.
Surah Al-Kahf(18:5)
