53:30
ذَٰلِكَ مَبْلَغُهُم مِّنَ ٱلْعِلْمِ ۚ إِنَّ رَبَّكَ هُوَ أَعْلَمُ بِمَن ضَلَّ عَن سَبِيلِهِۦ وَهُوَ أَعْلَمُ بِمَنِ ٱهْتَدَىٰ
That is their sum of knowledge. Indeed, your Lord is most knowing of who strays from His way, and He is most knowing of who is guided.

وَمَا لَهُم بِهِ مِنْ عِلْمٍ
(But they have no knowledge thereof.) meaning, they have no correct knowledge testifying to their statements. What they say is all lies, falsehood, fake and utter atheism,
