Allah(swt), Knows everything

 ذَلِكَ مَبْلَغُهُم مِّنَ الْعِلْمِ إِنَّ رَبَّكَ هُوَ أَعْلَمُ بِمَن ضَلَّ عَن سَبِيلِهِ وَهُوَ أَعْلَمُ بِمَنِ اهْتَدَى 53:30

(Fathe Muhammad Jalandari)
ان کے علم کي انتہا يہي ہے. تمہارا پروردگار اس کو بھي خوب جانتا ہے جو اس کے رستے سے بھٹک گيا اور اس سے بھي خوب واقف ہے جو رستے پر چلا 53:30

(Muhammad Assad)
 53:30 which, to them, is the only thing worth knowing. 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.53:30

(Yousaf Ali)
 53:30 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.53:30
