ذَٰلِكَ مَبۡلَغُهُم مِّنَ ٱلۡعِلۡمِ ۚ إِنَّ رَبَّكَ هُوَ أَعۡلَمُ بِمَن ضَلَّ عَن سَبِيلِهِۦ وَهُوَ أَعۡلَمُ بِمَنِ ٱهۡتَدَىٰ
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.<br/>
That, namely, the desire of this world, is the full extent of their knowledge, that is, the limit of their knowledge, namely, that they have preferred this life to [that of] the Hereafter. Truly your Lord knows best those who have strayed from His way, and He knows best those who are [rightly] guided: He has knowledge of both and will requite both.
