﴿ 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!”

They say nothing but a lie.
