We relate to thee their story in truth: they were youths who believed in their Lord, and We advanced them in guidance: 13 and strengthened their hearts when they stood up and proclaimed: "Our Lord is the Lord of the heavens and the earth. We shall call upon no other god beside Him; (for if we did so), we shall be uttering a blasphemy." 14 These our people have taken to them other gods, apart from Him. Ah, if only they would bring some clear authority regarding them! But who does greater evil than he who forges against God a lie? 15 “And when you have disassociated yourself from them and all what they worship besides Allah – so take refuge in the Cave – your Lord will spread His mercy for you and arrange ease for you in your affairs.” 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
