We tell you this story for a genuine purpose. They were young people who believed in their Lord and We gave them further guidance. 13 And We strengthened their hearts, when they stood up and said, 'Our Lord is the Lord of the heavens and earth; we will not call upon any god, apart from Him, or then we had spoken outrage. 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 and who doth greater wrong than he who fabricateth against God a lie? 15 Hence, now that you have withdrawn from them and from all that they worship instead of God, take refuge in that cave: God will spread His grace over you, and will endow you - whatever your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 ۞ 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
