Quran 18, Al-Kahf (The Cave) ⓘ
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.
مَا لَهُمْ بِهِ مِنْ عِلْمٍ وَلَا لِآبَائِهِمْ كَبُرَتْ كَلِمَةً تَخْرُجُ مِنْ أَفْوَاهِهِمْ إِنْ يَقُولُونَ إِلَّا كَذِبًا
