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 gods besides Him; why do they not produce any clear authority in their support? Who is then more unjust than he who forges a lie against Allah? 15 And when you forsake them and what they worship save Allah, betake yourselves for refuge to the cave; your Lord will extend to you largely of His mercy and provide for you a profitable course in your affair. 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
