“Muhammad was a Persian General that went to a monastery in Syria”
That makes NO sense. Muhammad then would not know Arabic since neither Persians nor Syrians spoke it.
Maybe, but again, I don’t have the text that I read...memory is flawed.
But I believe I am remembering the description of the letter correctly.
Remember, before the rise of the Roman Empire, the Persian Empire ruled a huge piece of the world. Their Empire included hundreds if not thousands of languages.
