See how idolatrous they are!  They want prophetic ministry like the Jews had.  They had to claim the last prophet, like the Jews had John the Baptist  They wanted to have a holy place like the Jews had. They built a mosque on a captured hill in the land of the Jews. They wanted and still want global influence like the Jews had. So they invented a book like the Jews have. Where this greed ends is clear from Christian ethics.

Covetousness is idolatry

When the 7th century Arabs came to learn a few things orally about the Jews and their God they thought they saw an opportunity to have something similar. Driven by unhinged jealousy and greed they now have their own prophet, book and holy places. The collapse is evident. The greed stands out. Islam is a mountain of covetousness.

Therefore, treat the parts of your earthly body as dead to sexual immorality, impurity, passion, evil desire, and greed, which amounts to idolatry. (Colossians 3:5, NASB)
