Sort of correct. It is certainly much closer to the original Islam of Moh and his immediate successors.
Here's one way to think of it. Our Civil War was in essence fought over what the genuine America was or would become. Both sides had entirely logical reasons for their belief that their POV was that of the "real" America.
Since neither side would back down, the only way to settle what "the genuine America" would be was the way it was settled.
Same for Islam. Only Muslims can define what "real Islam" is and that definition will almost certainly be settled only by war.
“Islam IS as Islam DOES.”
Or as Jesus says, “By their fruits ye shall know them.”
Questions?
They already did that back in the 8th-9th centuries. This is why the "traditional" understanding of the Qur'an, the ahadith, the sunnat, the isnad, and the rest are accepted as "traditional."
