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 now that you have dissociated yourselves from them and from whatever they worship beside Allah, go and seek refuge in the Cave. Your Lord will extend His mercy to you and will provide for you the means for the disposal of your affairs." 16 ۞ The sun could be observed to incline away from their cave on the right, as it rose, and to turn away from them on the left, when it set, while they lay in the wide space inside the cave. This is one of the signs of God. He whom God guides is rightly guided; but for him whom He lets go astray, you will find no helper or guide. 17
