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. 13 and endowed their hearts with strength, so that they stood up and said [to one another]: "Our Sustainer is the Sustainer of the heavens and the earth. Never shall we invoke any deity other than Him: [if we did,] we should indeed have uttered an enormity! 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 And who is more unjust than one who invents about Allah a lie?" 15 "Now that you have withdrawn from them and from all that they worship instead of God, take refuge in that cave; your Lord will extend His mercy to you and will make fitting provision for you in your situation." 16 ۞ And thou mightest have seen the sun, when it rose, inclining from their Cave towards the right, and, when it set, passing them by on the left, while they were in a broad fissure of the Cave. That was one of God's signs; whomsoever God guides, he is rightly guided, and whomsoever He leads astray, thou wilt not find for him a protector to direct. 17
