It doesn’t matter if Mo existed or not.
The fact that over a billion moslems believe he did is the point.
Trying to disprove that Mo existed to moslems is akin to trying to put out fire with gasoline.
Besides, Mo’s (alleged) disciple “Umar” did exist. We know that from historical accounts of Iran’s invasion by bedo Arabs. “Umar” is/was said to be one of Mo’s immediate disciples, but when Umar & his army attacked Iran, Mo wasn’t in the picture (he had already died, several yrs earlier).
By all accounts, Mo or his disciples were bedo Arabs and were illiterate.
As for the Quran, it has been rewritten several times, since Mo & Umar’s time, over the centuries. It couldn’t have been originally written by Mohamad.
Plus the Quran is a mish mash of preceding ‘holy’ books. IMO, that’s why in parts it is disjointed, fragmented, and just doesn’t make sense.
The original Arabic version was written in Egyptian arabic, I read somewhere a while ago - this was written a couple of centuries, I think, after Mo’s death (anyhow it was definitely written *after* Mo’s death).
The Saudi only accept the version written in Saudi arabic as the “official” one. Then again, the Saudi Royal family are the “official” custodians of the “holy” cities of Mecca & Medina. And, Saudi Arabia is the birthplace of Mo... well, allegedly.
But, I do believe Mohamad did exist & declared himself a “prophet”, once upon a time.
Have you heard about an ancient koran found in Germany which shows different passages from the officially accepted koran of today?
The older extant Korans have a Hebrew inscription at the end, saying that “this is all nonsense”. We have a tradition that that was snuck in by Mo’s Jewish secretary. I believe he was a specific person, suffering from epilepsy and fed up with the idiotic beliefs of Arabs at that time, and enamored with Christian and Jewish stories and theology. He was also an egomaniacal mass murderer. Presently reading Twilight Over Delhi by a distinguished Muslim of letters, contemporary of Ghandi, and he is quite right that imperialistic interference with native cultures leaves irreversible harm in its wake. The same goes for the most imperialistic religion of all, Islam, destroying indigenous cultures for 1,400 years and counting.
