This is more about the history of Islam, you should watch it first before commenting.
Also it sounds like you're trying to control access to the religion when anybody can read the verses about disbelievers. How do you reconcile this when most scholars explains them as the Quran reads it and we see it acted out in the world today?
No, Islam is narrated from the source to the Prophet by the Angel Jibril (Gabriel) and then past down through generations of scholars, recorded by who and when, from the time of the prophet to his companion without any deviations in linguistic and narration until todays scholars. Who teach who, from where and when, all documented since 1400+ years ago, got the chain of names.
That's how the knowledge is preserved. It's not about controlled access by scholars as you put it.
It's about preserving the message as previous scriptures was not preserved as intended.
Don't need to believe me, ask any scholars registered under PERGAS which is registered and affliated by MUIS.
Too many falsehood (especially online), which is one of the prophecies (from 1400 years ago) of the many signs of the End of Days in Islam.
Sharing of knowledge is caring. Chillax.
