There is no reference whatsoever in the Koran to Jerusalem or the al aksa mosque. Supposedly Mohammed dreamed he visited Jerusalem, but never set foot there. The only reason Jerusalem has any importance to muslims at all is because they know that it legitimately belongs to the Jewish people & is Judaism's holiest place, so this threatens & prevents them from having absolute control over the entire region. Obviously, no Israeli government would ever tear it down out of fear of insulting Islam & causing a war, but maybe G-d in his infinite wisdom will set-off an earthquake that will bring it down once & for all. If there's no mosque, that's one less thing to fight over.
