Translation endnotes
[18:9-27] These 19 verses contain numerous key words that strongly imply that the story of the cave have double meaning like the verses in chapter 74, and the second meaning is about a prophetic event. I have already observed examples of a hidden mathematical design, and God the most Wise will unveil it when the right time comes.
