18.21 - And thus did We cause them to be found that they (who found them) might know that the promise of Allah is truthful and that for the hour, there is no doubt about it. When they disputed among themselves about their affair and said: Build over them a structure, their Lord is most Knowing of them. Those who prevailed in their affair said: We will surely take over them a mosque. 18.22 - They will say: Three, their fourth is their dog; and (others) say: Five, their sixth is their dog, guessing the unknown. And (others) say: Seven and their eighth is their dog. Say: My Lord is most Knowing their count; none knows them except a few. So do not argue about them except with an obvious argument and do not ask about them anyone among them. 18.23 - And do not say of anything: Indeed, I will do that tomorrow. 18.24 - Except if Allah wills. And remember your Lord when you forget and say: Hopefully my Lord will guide me to what is nearer than this to guidance. 18.25 - And they remained in their cave three hundred years and were increased by nine. 18.26 - Say: Allah is most Knowing how long they remained. To Him belongs the unknown of the heavens and the earth. How Seeing is He and how Hearing. They do not have other than Him any guardian; and He does not associate with His judgment anyone. 18.27 - And recite what has been revealed to you from the book of your Lord, there is no changing to His words. And never will you find in other than Him a refuge. 18.28 - And be patient with those who call upon their Lord in the morning and the evening; they desire His direction. And let not your eyes pass beyond them; you desire the adornment of the life of this world, and do not obey one whose heart We have made unaware of Our remembrance and who follows his desire and whose affair is ever negligent. 18.29 - And say: The truth is from your Lord, so whoever wills let him believe, and whoever wills let him disbelieve. Indeed, We have prepared for the unjust people a fire whose walls will surround them; and if they call for help, they will be helped with water like molten brass which scalds the faces. Miserable is the drink and bad is the resting place. 18.30 - Indeed, those who have believed and done good deeds, indeed, We will not waste the reward of any who did good in deed.
