all faithful Muslims will have been raptured off the planet. The rest will have to fight and die 'honorably' to attain heaven (martyrdom is a get-out-of-jail-free card, you know).
There is a bit about it here.
Forgive me if I am vague - it has been many years since I last took a crack at the koran and hadiths. But the destruction of the ka'ba (and in places, Mecca, is part of their prophetic expectations.
