Quran 53:30

This is the farthest limit of their knowledge. Surely your Lord alone knows best who has strayed away from the path and who has come to guidance.

That is the ultimate reach of their knowledge. Indeed your Lord knows best those who stray from His way, and He knows best those who are [rightly] guided.

This is the extent of their knowledge; indeed your Lord well knows one who has strayed from His path, and He well knows one who has attained guidance.

That is their attainment of knowledge. Surely thy Lord knows very well those who have gone astray from His way, and He knows very well those who are guided.

That (is) their sum of knowledge. Indeed, your Lord (is) He (Who) knows best (he) who strays from His Path, and He knows best (he) who is guided.

That is their highest point of knowledge. Verily thine Lord! it is He Who is the Best Knower of him who strayeth from His way, and He is the Best Knower of him who letteth himself be guided.

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.

that being the utmost of their knowledge. Surely your Lord fully knows those who have strayed away from His Path and He also fully knows those who are rightly guided.

This is what the extent of their knowledge amounts to. Your Lord knows best who has gone astray from His path and who has been rightly guided.

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.

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.

That is all they have of knowledge. Your Lord knows best who has strayed from His Path, and those who are guided.

That is their sum of knowledge. Indeed, your Lord is most knowing of who strays from His way, and He is most knowing of who is guided.

That is the extent of their knowledge. Your Lord knows best who has strayed from His path, and He knows best who has accepted guidance.

That is the ultimate extent of their knowledge. Surely your Lord knows best those who stray from His path and He knows best those who follow His guidance.

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.
