We relate to you their story with the truth; surely they were youths who believed in their Lord and We increased 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 But who does greater evil than he who forges against God a lie? 15 And now when ye have withdrawn from them and that which they worship, except God, betake yourselves to the cave; your Lord will unfold for you some of His mercy, and will prepare for you of your affair an easy arrangement. 16 ۞ And you might see the sun when it rose, decline from their cave towards the right hand, and when it set, leave them behind on the left while they were in a wide space thereof. This is of the signs of Allah; whomsoever Allah guides, he is the rightly guided one, and whomsoever He causes to err, you shall not find for him any friend to lead (him) aright. 17
