...there are only 4 nations that you can call "Muslim" nations: Pakistan, Iran, Afghanistan, and Mauritania in Africa.
This web page:
Muslim world - Wikipedia
gives a list of 47 countries in which Muslims make up the majority.
Of these 47, 7 are listed as "Islamic State" and 17 list Islam as "State Religion."
Don't think I'd want to live in any of those, and probably not even visit.
This brings to mind a passage from George Bernard Shaw's
Caesar and Cleopatra (1898):
CAESAR (recovering his self-possession): Pardon him. Theodotus: he is a barbarian, and thinks that the customs of his tribe and island are the laws of nature.
Religious belief does not constitute scientific evidence, nor does it convey scientific knowledge.
