(Al-Kahf) 18 : 17
وَتَرَى الشَّمْسَ إِذَا طَلَعَتْ تَزَاوَرُ عَنْ كَهْفِهِمْ ذَاتَ الْيَمِينِ وَإِذَا غَرَبَتْ تَقْرِضُهُمْ ذَاتَ الشِّمَالِ وَهُمْ فِي فَجْوَةٍ مِنْهُ ۚ ذَٰلِكَ مِنْ آيَاتِ اللَّهِ ۗ مَنْ يَهْدِ اللَّهُ فَهُوَ الْمُهْتَدِ ۖ وَمَنْ يُضْلِلْ فَلَنْ تَجِدَ لَهُ وَلِيًّا مُرْشِدًا

And you would see the sun when it rose, inclining away from their cave on the right, and when it sets, passing away from them on the left, while they were within an open space thereof. That was from the Signs of Lord Allah. The one whom Allah guides are guided, but the one whom He lets to stray, you will never find a protecting guide for him.

Three-Time-Knower Lord arranged the cave in such a way that the temperature will not increase because of the sunlight. Only believer will try to identify the Lord by utilizing Adhikr.

Today, Adhikr is formed as the Best Interpretation of Lord’s Book and Lord has become the Impartial. So whoever testifies Adhikr, he is guided for his sake; and whoever strayed from It, its loss is for herself as explained in verse 10: 108. See explanation 2: 119; 7: 37 and 178-179.
