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 made their hearts steadfast when they stood up and said, “Our Lord is the Lord of the heavens and the earth – we shall not worship any other deity except Him – if it were, we have then said something excessive.” 14 Our people have considered other things equal to God. Why cannot they present clear proof in support of their claim. Who is more unjust than one who invents falsehood against God?" 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 ۞ And [for many a year] thou might have seen the sun, on its rising, incline away from their cave on the right, and on its setting, turn aside from them on the left, while they lived on in that spacious chamber, [bearing witness to] this of God's messages: He whom God guides, he alone has found the right way; whereas for him whom He lets go astray thou canst never find any protector who would point out the right way. 17
