His declaration was probably based on the fact that while having epileptic seizures, he would have visions of the subject matter he discussed with the aforementioned priests, rabbis and Zoroastrian whatchamacallits. Then there is the fact that Arabic is a very poetic, rhetorical language, and that people who speak it as a first language are therefore easily persuaded by strong rhetoric, the feeling of excitement in the hearer replacing facts and logic as a persuasive medium.
You’re probably right about Mo having epileptic seizures, or suffering from some type of psychosis... to me Arabic sounds like a very harsh and throaty language, not very pleasing to the ear. Then again, I don’t speak or understand it.
