There would have been a Arab war lord, or tribal leader that would have fitted Mohammad's description which they used in the narrative
but as for Mohammad a prophet that began Islam, No
the historical records that have come to light show that the story of Islam was a story redacted over several centuries so that the Arabs could have a competing prophetic claim to the Jews and Christians.
Their early Mosques faced Petra there is no early mention of Mohammad or Allah when the Arabs over run Constantinople no mention within official documents by the Arabs themselves but a development over time to create a competing religion.
Islam has been shown conclusively to have no legitimacy and their god Allah has for all intense purposes fallen,
this century could very well be the last for any meaningful thinking Muslim to exist as the evidence of these historical and archaeological proofs becomes more widely known and cultural tradition although tightly held by the Islamic community will slowly die off along with their already fallen god Allah.
