The Islamic "Jannah" is a mockery of the true Christian Heaven. The pagans of the time of Muhammad were overly materialistic and lustful, and observing this - Muhammad would appeal to their hedonistic and pagan worldview, telling them that if he followed him, heaven would be full of beautiful virgins to sleep with and delightful food to feast on: the saved "will have whatever they wish for, forever"; (Q.25:16).
However we Catholics know that disconnecting ourselves from the sinful vices of lust and gluttony is how we live a Holy life, and how we are able to reach God's eternal Kingdom.
