Surah Al-Kahf

[All] praise is [due] to Allah, who has sent down upon His Servant the Book and has not made therein any deviance

[He has made it] straight, to warn of severe punishment from Him and to give good tidings to the believers who do righteous deeds that they will have a good reward

In which they will remain forever

And to warn those who say, "Allah has taken a son

They have no knowledge of it, nor had their fathers. Grave is the word that comes out of their mouths; they speak not except a lie

Then perhaps you would kill yourself through grief over them, [O Muhammad], if they do not believe in this message, [and] out of sorrow

Indeed, We have made that which is on the earth adornment for it that We may test them [as to] which of them is best in deed

And indeed, We will make that which is upon it [into] a barren ground

Or have you thought that the companions of the cave and the inscription were, among Our signs, a wonder

[Mention] when the youths retreated to the cave and said, "Our Lord, grant us from Yourself mercy and prepare for us from our affair right guidance

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 Muhammad], their story in truth. Indeed, they were youths who believed in their Lord, and We increased them in guidance
