﴿ مَّا لَهُم بِهِۦ مِنْ عِلْمٍۢ وَلَا لِءَابَآئِهِمْ ۚ كَبُرَتْ كَلِمَةًۭ تَخْرُجُ مِنْ أَفْوَٰهِهِمْ ۚ إِن يَقُولُونَ إِلَّا كَذِبًۭا ﴾

“No knowledge whatever have they of Him, and neither had their forefathers: dreadful -is this saying that comes out of their mouths, [and] nothing but falsehood do they utter!”

((A thing) whereof they have no knowledge) they have no proof or argument for what they claim, (nor (had) their fathers) nor did their fathers have any knowledge. (Dreadful is the word) dreadful is the word of idolatry (that cometh out of their mouths) that is uttered by their mouth. (They speak naught but a lie) about Allah.
