They can all converts to Islam. Not much changes since the 7th century. It allows wealth, polygamy and slavery. Now the Jacobin wont dare do some kind of exegesis... it would be deemed blasphemy.
Feel free to seek out what the sharia has to say about usury (strictly forbidden) and what Islam considers a good way to use wealth (hint: giving to the poor, building orphanages, madrasa and mosques, doing pilgrimages). You will be hard pressed to find a monotheist religion which really likes the rich to be honest.
I’m not going to give you about an explanation about all the way Islam has changed and become multiples since the 7th century because that would require a book length essay rather than a paragraph but you get my point.
