Or: "abundance of water" - which, according to many philologists (cf. Taj al= Aras), is one of the meanings of `ayn (primarily denoting a "spring"). As for my rendering of the phrase "he found it (wajadaha) setting...", etc., as "it appeared to him that it was setting", see Razi and Ibn Kathir, both of whom point out that we have here a metaphor based on the common optical illusion of the sun's "disappearing into the sea"; and Razi explains this, correctly, by the fact that the earth is spherical. (It is interesting to note that, according to him, this explanation was already advanced in the - now lost - Qur'an-commentary of AN `All al-Jubba i, the famous Mu'tazili scholar who died in 303 H., which corresponds to 915 or 916 of the Christian era.)[/INDENT]
Along the same lines:
The verses narrate part of the story of Zul-Qarnain. Being a great traveller Prophet Zul-Qarnain eventually, at sun set, arrived at a place where there were springs of vast murky waters. He found around it tribes of people, some righteous and some malign. The narration goes on to describe how Zul-Qarnain was given authority to rule over them as a just king. It narrates the version of events as he, Zul-Qarnain saw them – he saw the sun set in a murky water, nothing wrong with that. The second verse narrates that Zul-Qarnain turned another direction and travelled on until he saw the sun rise and it just so happens that he saw it rise on a people who were without shade. Again, a very simple narration, no claim of being scientific fact.
The critics who raise this issue and claim that the God of the Quran does not know the simple scientific that the sun never actually sets are barking up the wrong tree. The above verses in no way make the claim of being scientific fact as God sees it. We don’t see God making the claim that the sun sets into murky waters! Or rises on a certain group of people. We simply see God describing things as witnessed by Zul-Qarnain - "They ask thee concerning Zul-Qarnain. Say, "I will rehearse to you something of his story". The sun sets wherever you see it set. If you are on a beach you will see it set into the ocean. If you are on a hill, you will see it set behind the hill.
