The spread of islam to central asia and parts of south asia illustrates which of these concepts?

Religion Expanding

Explanation:

   Islamic expansion increased through a link between the trade relationship and the good coexistence and treatment among its supporters, who through their aficionados demographically expanded the number of their religious honors, who were part of this condescending means of negotiation.

  And in a consolidation of the formation of this medium, it is due to many of its former leaders, in their exorbitant displays of exuberance, who spread their riches through what was their extravagance, to better devalue what was of others, in order to value what was his property, to better market what belonged to him.

    And in these directions, the Islamic religion was gaining ground, and winning more and more loyal collaborators, and this was fundamental to the increase of its population size that is today.
