وَتَرَى الشَّمسَ إِذا طَلَعَت تَزاوَرُ عَن كَهفِهِم ذاتَ اليَمينِ وَإِذا غَرَبَت تَقرِضُهُم ذاتَ الشِّمالِ وَهُم في فَجوَةٍ مِنهُ ۚ ذٰلِكَ مِن آياتِ اللَّهِ ۗ مَن يَهدِ اللَّهُ فَهُوَ المُهتَدِ ۖ وَمَن يُضلِل فَلَن تَجِدَ لَهُ وَلِيًّا مُرشِدًا

You would have seen the sun, as it rose, veering away from their cave to the right, and as it set, bypassing them to the left, while they lay within the spacious area of the cave. This was one of God’s signs. Whomever God guides is guided, and whomever He leaves to stray, you will find no guiding mentor for him.
