18:17You would have seen the sun, when it rose, veering away from their cave towards the right, and when it sets, moving away from them to the left, as they lay in the midst of the cave. That was one of God’s wonders. He whom God guides is truly guided; but he whom He misguides, for him you will find no directing friend.

18:57Who does greater wrong than he, who, when reminded of his Lord’s revelations, turns away from them, and forgets what his hands have put forward? We have placed coverings over their hearts, lest they understand it, and heaviness in their ears. And if you call them to guidance, they will not be guided, ever.

18:104“Those whose efforts in this world are misguided, while they assume that they are doing well.”
