30ذٰلِكَ مَبلَغُهُم مِنَ العِلمِ ۚ إِنَّ رَبَّكَ هُوَ أَعلَمُ بِمَن ضَلَّ عَن سَبيلِهِ وَهُوَ أَعلَمُ بِمَنِ اهتَدىٰMuhammad Asadwhich, to them, is the only thing worth knowing.1 Behold, thy Sustainer is fully aware as to who has strayed from His path, and fully aware is He as to who follows His guidance.Lit., "that is their sum-total [or "goal"] of knowledge".
