I do not know.
I did find this
"... While still in his teens, Muhammad accompanied his uncle on trading journeys to Syria, gaining experience in commercial trade, which was the only career open to him as an orphan. Islamic tradition states that when Muhammad was either nine or twelve, while accompanying a caravan to Syria he met a Christian monk or hermit named Bahira, who is said to have foreseen Muhammed’s career as a prophet of God. Little is known of Muhammad during his later youth; available information is fragmented, and it is difficult to separate history from legend. It is known that he became a merchant and “was involved in trade between the Indian ocean and the Mediterranean Sea.” Due to his upright character during this time, he acquired the nickname “al-Amin,” meaning “faithful, trustworthy,” and “al-Sadiq,” meaning “truthful.”

So a Christian Monk may have been the Elijah?
Ali should have been the One all turned to after the passing of Muhammad. When those who wanted power said Ali was too young, they took the Faith of Muhammad in the direction they wanted and not the direction according to Muhammad's Covenant.
That is why in Revelation we read that Islam became a dead body laying in the street for 1260 years.
All this is available to study. I wonder why people do not?
