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 We strengthened their hearts, when they rose up and declared, "Our Lord is the Lord of the heavens and the earth. Never shall we call upon any deity other than Him: for that would be an outrageous thing to do. 14 (Then they conferred among themselves and said): "These men, our own people, have taken others as gods beside Him: why do they not bring any clear evidence that they indeed are gods? Who can be more unjust than he who foists a lie on Allah? 15 And when ye withdraw from them and that which they worship except Allah, then seek refuge in the Cave; your Lord will spread for you of His mercy and will prepare for you a pillow in your plight. 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
