Also (from the book I linked to):

According to the famous historian Tabari, the Prophet of Islam is reported to have said:

"Allah created the mountain Qaf all around the Earth. It is called stake of the Earth, as it is said in the Quran, 'And the mountains as pegs?' This world is in the middle of the mountain of Qaf as the finger is in the middle of the ring. No man can reach there, for he needs to spend four months in the darkness, In this mountain there is no sun, no moon no stars and it is so blue that the azure colour of the sky is the brightness of the mountain Qaf that reflects on the sky, and it appears this colour, If this was not so, the sky would not be blue. All the mountains that are seen in this world are from the mountain Qaf. ...

Qaf is the arabicized form of the Persian word "Gap" which means "Unknown", it is interesting to know that the oldest mention of an Unknown Mountain is in an inscription of Shapur I (241-272 AD) for the mounatins between the Black Sea and the Caspian Sea. He has mentioned it Gapkuh ("Unknown Mountain" Gap=Unkown & Kuh=Mountain) = Arabic Qafqaz = Russian KAVKAZ = English Caucasus
