Surah Al-Kahf Ayahs #15 Translated in English

So We cast [a cover of sleep] over their ears within the cave for a number of years.

Then We awakened them that We might show which of the two factions was most precise in calculating what [extent] they had remained in time.

It is We who relate to you, [O Muḥammad], their story in truth. Indeed, they were youths who believed in their Lord, and We increased them in guidance.

And We bound [i.e., made firm] their hearts when they stood up and said, "Our Lord is the Lord of the heavens and the earth. Never will we invoke besides Him any deity. We would have certainly spoken, then, an excessive transgression.

These, our people, have taken besides Him deities. Why do they not bring for [worship of] them a clear evidence? And who is more unjust than one who invents about Allāh a lie?"
