Qur’an teaches us that the Sun sets in a muddy spring:
018.086 Till, when he reached the setting-place of the sun, he found it setting in a muddy spring, and found a people thereabout. We said: O Dhu’l-Qarneyn! Either punish or show them kindness.
018.090 Till, when he reached the rising-place of the sun, he found it rising on a people for whom We had appointed no shelter therefrom.
Serious scientific errors here! Firstly, it is scientifically accepted fact that, the Sun never go down in a muddy spring. Secondly, this seems to presuppose a FLAT Earth, otherwise how can there be an extreme point in the West or in the East? A sunrise there would be basically just the same as at any other place on this earth, at land or sea. It would still look as if it is setting “far away”. It does say, that he reached THE PLACE where the Sun sets and in his second Journey the place where it rises.
