Inspired by the thread "Western Islam" further down the page, what would Islam look like if the Byzantine Empire was conquered during the first wave of the Islamic invasions? Let's assume that Persia loses Mesopotamia but manages to survive behind the Zagros mountains. I'm not looking for the political effects of this, I'm more focused on the cultural effects (what would the people eat, what languages would they speak, how would they worship..etc)
So, what would Islam look like with a large amount of Greek influence rather than Persian?
