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 We strengthened their hearts, when they rose up and declared, "Our Lord is the Lord of the heavens and the earth. Never shall we call upon any deity other than Him: for that would be an outrageous thing to do. 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 and who doth greater wrong than he who fabricateth against God a lie? 15 And now when ye have withdrawn from them and that which they worship, except God, betake yourselves to the cave; your Lord will unfold for you some of His mercy, and will prepare for you of your affair an easy arrangement. 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
