Arabia in Mohammed's time would have been largely unoccupied (much like today) with the occasional cities dotting the landscape. In the cities, there would have been marketplaces where people would sell wares, shrines for different gods venerated by the different tribes in the city, and numerous militias to defend the different tribes.
