Which noble Qur'anic verse describes how the sun avoids the cave where the People of the Cave sleep at its rising and setting, and describes them as being in a spacious part of the cave, and mentions that this is among the signs of Allah, and that whoever Allah guides is the guided, and whoever He leaves astray—for them you will never find a protecting friend to lead them to the right way?

The verse (17) from Surat Al-Kahf speaks about the People of the Cave, where Allah Almighty mentions that when the sun rises, it inclines away from their cave to the right, and when it sets, it departs from them to the left. This is to protect them from its heat and rays, while they are turned over in the cave, right and left. This is evidence of Allah's power and the greatness of His signs.
