We will relate to thee their tidings truly. They were youths who believed in their Lord, and We increased them in guidance. 13 And We braced their hearts when they stood forth and said: our Lord is the Lord of the heavens and the earth; never we shall call upon a god beside him; for then we shall be saying an abomination. 14 These people of ours have taken to worshipping [other] deities instead of Him, without being able to adduce any reasonable evidence in support of their beliefs; and who could be more wicked than he who invents a lie about God? 15 Hence, now that you have withdrawn from them and from all that they worship instead of God, take refuge in that cave: God will spread His grace over you, and will endow you - whatever your [outward] condition - with all that your souls may need! 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
