You're going to have some difficulty there. the Quryash held a monopoly of power over the course of the Rashidun and beyond. They are the tribe that controlled the Kabba and became wealthy from that, and many of the power-players at this time are early followers of the prophet and they got their position from that.

I suppose there are some small Muslim groups sent over into Abyssania I wouldn't know enough about. Otherwise there's the Lahkmids.
