During early Arabia the belief was more celestial. Sufism still holds true with its spins. But counterfeit Islam made a kabaa and made people walk around kabaa. This externilized Islam. Instead of intent was for internal.

This is why prayer was introduced. An outward expression to a man made object kabaa.

Islam basically used truth to draw people in, then when had power of it all. They made it into a business.

Hajj is a huge tourist destination for Muslims. Who gets all the money?? Saudi Arabia.

So more converts = more money tourism
