I've come across more information about it.

Heres a book which talks about it a little bit: http://books.google.com.au/books?id=...untain&f=false

Also while searching I found this statement of Ibn Kathir in his Tafsir of Suratul-Qaf:

It has been narrated from some of the salaf that they said, “Qaf is a mountain that surrounds the whole earth, and it is called Mount Qaf!” And it is as if this, and Allah knows best, is from the superstitions of the Children of Isra’il that some of the people took from them, because of their considering it to be permissible to narrate from them that which is not affirmed nor rejected. I think that this and its likes are from the forgery of some of the Zanadiqah (Heretics who seek to undermine the religion) amongst them who deceive the people concerning the matter of their religion, just as hadiths have been fabricated upon the Prophet in this Ummah – despite the great status of its scholars, Huffaz, and Imams – even though it has not been such a long time. So how about the nation of Bani Isra’il, what with the great time that has passed, the lack of precise Huffaz amongst them, their drinking alcoholic drinks, their scholars twisting the words from their places and changing Allah’s Books and Verses.

The Legislator only permitted narrating from them in his statement, ‘Relate from the Children of Isra’il, and there is no sin in that,’ concerning that which the intellect can conceive, but as for what the intellects find to be impossible, and it is deemed falsehood, and it is fairly obvious that it is a forgery – then it is not included in that. I do find this somewhat confusing as to how it is meant to be understood. It seems to be described as something in this physical world - but if thats the case then it seems to draw the world in a different way (i.e. flat). On the other hand it seems that it could be a place in another spiritual dimension or whatever you want to call it.

It would be good to hear a scholarly explanation about it.
