53:30
ذَٰلِكَ مَبْلَغُهُم مِّنَ ٱلْعِلْمِ ۚ إِنَّ رَبَّكَ هُوَ أَعْلَمُ بِمَن ضَلَّ عَن سَبِيلِهِۦ وَهُوَ أَعْلَمُ بِمَنِ ٱهْتَدَىٰ
dhālika mablaghuhum mina l-ʿil'mi inna rabbaka huwa aʿlamu biman ḍalla ʿan sabīlihi wahuwa aʿlamu bimani ih'tadā
Their knowledge does not go beyond that. Your Lord knows best who strays from His path and who follows guidance.
That is what they could reach of knowledge. Verily, your Lord it is He Who knows best him who goes astray from His Path, and He knows best him who receives guidance.
