let's say what's in decline is the "moderate" Islam; most of the moderates are either going full extremist and bomb stuff or go full atheist/agnostic/deist/whatever.
In Azerbaijan, there's a saying: "culturally but not religiously Muslim". In short, this isn't happening in the good inlightened countries like Azerbaijan and Middle Asia and Turkey (you know better than me likely, but isn't Turkey one of the Muslim countries that bans veils in public schools?) with long tradition of laïcité:)
the "best" "objective" source of Islam(both political and as a whole) is Qur'an, it's the only unquestioned thing between Muslims.
Practice =/ doctorine.
