I mean who do you consider in this category
How could anyone call themselves Muslim, unless it's some sort of ideological standpoint (agnostic Muslims wink wink), while rejecting shariah? I've never met one. Unless thet viewed themselves as first non-believing, eho then became religious "born again", to eventually leaving it all together. Even met thugs who do drugs and other law breaking practices, along with morally "questionable" acts, still say (very vaguely) that they think "shariah is good".
