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 We made their hearts steadfast when they stood up and said, “Our Lord is the Lord of the heavens and the earth – we shall not worship any other deity except Him – if it were, we have then said something excessive.” 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 "When ye turn away from them and the things they worship other than Allah, betake yourselves to the Cave: Your Lord will shower His mercies on you and disposes of your affair towards comfort and ease." 16 ۞ Thou wouldst have seen the sun, when it rose, declining to the right from their Cave, and when it set, turning away from them to the left, while they lay in the open space in the midst of the Cave. Such are among the Signs of Allah: He whom Allah, guides is rightly guided; but he whom Allah leaves to stray,- for him wilt thou find no protector to lead him to the Right Way. 17
