As others have pointed out... There are no muslims in the future...

Oh, I almost forgot. There are Muslims in the Enders Game series too. Not many though...most were vaporized. In what may yet turn out to be a prophetic bit of fiction, the middle eastern states launched WWIII against the west and were nuked into near oblivion. They still exist, and as the story reveals are still quite slimy, but they are far, far fewer in number.

For a series of books that specifically uses Muslims "fleeing from burning Mecca" as a protagonist, see the S.M. Stirling/David Drake series, THE GENERAL. There are five books in the series, all dealing with the societies on a planet cut-off from the rest of human civilization and its fall to barbarity and rise to a new civilization.
