Al-Kahf 5

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

mā lahum bihi min ʿil'min walā liābāihim kaburat kalimatan takhruju min afwāhihim in yaqūlūna illā kadhiban

They have no knowledge of it, nor had their fathers. Grave is the word that comes out of their mouths; they speak not except a lie.
