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 besides Him deities. Why do they not bring for [worship of] them a clear authority? And who is more unjust than one who invents about Allah a lie?" 15 (The young men said to one another): "And when you withdraw from them, and that which they worship, except Allah, then seek refuge in the Cave, your Lord will open a way for you from His Mercy and will make easy for you your affair (i.e. will give you what you will need of provision, dwelling, etc.)." 16 ۞ And you might have seen the sun, when it rose, declining to the right from their Cave, and when it set, turning away from them to the left, while they lay in the midst of the Cave. That is (one) of the Ayat (proofs, evidences, signs) of Allah. He whom Allah guides, is rightly guided; but he whom He sends astray, for him you will find no Wali (guiding friend) to lead him (to the right Path). 17
