Quran 18:17 — The Cave (Al-Kahf)

You could see the sun when it rose coming from the right side of their cave, and when it set, it shone on them from the left, as they slept in the hollow thereof. This is one of GOD's portents.* Whomever GOD guides is the truly guided one, and whomever He sends astray, you will not find for him a guiding teacher.

[18:16] "Since you wish to avoid them, and their worshiping of other than GOD,* let us take refuge in the cave. May your Lord shower you with His mercy and direct you to the right decision."

[18:18] You would think that they were awake, when they were in fact asleep. We turned them to the right side and the left side, while their dog stretched his arms in their midst. Had you looked at them, you would have fled from them, stricken with terror.
