So We sealed upon their ears in the cave for a number of years.
Translation endnotes
[18:8-12] The young monotheists, wrongly known as the "seven sleepers," are closely connected to the end of the world, as it is expressed in 18:9-21. [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. When the secrets contained in the cave is revealed by divine permission, it will prove once again the truth in the assertion at 18:27.
