It does not name any religion but allows people to opt out on the basis of religious beliefs. Islam is against gambling and if you personally knew any Muslims, you would know how much angst they go through when it comes to auto insurance.

So, yes, Muslims would fall in that category.
Then it’s time to form a new Christian sect which abhors gambling.
