ذَلِكَ مَبْلَغُهُم مِّنَ الْعِلْمِ إِنَّ رَبَّكَ هُوَ أَعْلَمُ بِمَن ضَلَّ عَن سَبِيلِهِ وَهُوَ أَعْلَمُ بِمَنِ اهْتَدَى
[53:30]
That is their goal of knowledge; surely your Lord knows best him who goes astray from His path and He knows best him who follows the right direction.
That is as far as knowledge will reach them. Verily thy Lord knoweth best those who stray from His Path, and He knoweth best those who receive guidance.
Such is their sum of knowledge. Lo! thy Lord is Best Aware of him who strayeth, and He is Best Aware of him whom goeth right.
