Islam is the official religion of the state

Isn't Anglicism the official religion of the UK?

"No law that contradicts with its rules can be promulgated."

Could mean Sharia, or it could mean that prostitution will be outlawed.

Yes, and I think Lutheranism is still the official state religion of Sweden, but obviously these nominal relationships have little if any impact on modern day legislation. Don't expect a similar arrangement in Iraq; sharia in some form or another will apply.
