We relate to thee their story in truth: they were youths who believed in their Lord, and We advanced 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 for themselves gods beside Him - wherefore bring they not for them an authority manifest? and who doth greater wrong than he who fabricateth against God a lie? 15 "Now that you have withdrawn from them and from all that they worship instead of God, take refuge in that cave; your Lord will extend His mercy to you and will make fitting provision for you in your situation." 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
