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 with patience, when they stood up and said: Our Lord is the Lord of the heavens and the earth; we will by no means call upon any god besides Him, for then indeed we should have said an extravagant thing. 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 (They were told), "Now that you have abandoned them and what they worship instead of God, seek refuge in the cave. God will, certainly, grant you mercy and provide you with help to safely get out of this trouble." 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
