Apparently according to them the first Muslims(Muhammad PBUH, his Family and the sahabas) and the Rashidun Caliphate formed part of the "True Church of God" of Arabia...Lots of things we may disagree on but it's pretty obvious...Though they have some pretty good opinion, they apparently used weak sources....looks weird but interesting to read...really weird...
Interesting quote:
"From the actual writings of the Koran, it seems that the man and his group were key players in this great struggle for independence and Bible truth over the Trinitarian heresies that were being formulated in the West. They were allied with the Sabbatarian Christians to the West. These Sabbatarians, called “Paulicians”, formed the buffer in Asia Minor (up to the Taurus Mountains) against the Trinitarians that were using the Eastern Empire at Constantinople as their base.
The pagans destroyed the message of the Koran as the Pharisees did with the OT, and as the Roman Empire-based Trinitarians"
