There is one Islam which is Static - Anyone going against this/challenging it/questioning it/refusing it is/has to be Eliminated.
That's how it has been going on since 632 AD.
Boss,
Muslims say whatever is written in Quran is 100% Correct Undisputed. You can't challenge that/question that.
You know what happens.
Even the so called Munafiqs wouldn't dare to challenge the above view, It is that Static!
Your talking about the literalist Islam like Wahabism?
Even they can't agree 100% with each other. No two human beings, despite their religion, will ever agree in Exigo with another.
Unless you have some type of pope authority figure whose arbitration is accepted as final, any type of religous goverment is impossible.
That's why Secularism is the best choice.
