﴿ كَذَٰلِكَ وَقَدْ أَحَطْنَا بِمَا لَدَيْهِ خُبْرًۭا ﴾

“thus [We had made them, and thus he left them; and We did encompass with Our knowledge all that he had in mind”

(So (it was)) just as he reached the West, so did he reach the East. (And We knew all concerning him) We knew what he had of information and exposition.
