We recount unto thee their tidings with truth. Verily they were certain youths who believed in their Lord, and We increased them in guidance. 13 And We strengthened their hearts, when they stood up and said, 'Our Lord is the Lord of the heavens and earth; we will not call upon any god, apart from Him, or then we had spoken outrage. 14 These, our people, have taken besides Him deities. Why do they not bring for [worship of] them a clear authority? And who is more unjust than one who invents about Allah a lie?" 15 [The youths said to one another], "And when you have withdrawn from them and that which they worship other than Allah, retreat to the cave. Your Lord will spread out for you of His mercy and will prepare for you from your affair facility." 16 ۞ And [for many a year] thou might have seen the sun, on its rising, incline away from their cave on the right, and on its setting, turn aside from them on the left, while they lived on in that spacious chamber, [bearing witness to] this of God's messages: He whom God guides, he alone has found the right way; whereas for him whom He lets go astray thou canst never find any protector who would point out the right way. 17
