The correct answer is: He was said to have received a message from an angel.
When meditating, Muhammad received a revelation from the Archangel Gabriel, who said he had been chosen as a prophet. He dedicated himself to preach the word of God, and the messages transmitted by Gabriel are recorded in the Quran .
Muhammad wasn't a militay leader before the revelation, and the vision of the angel wasn't while he was sleeping, also, there is not several muslim gods since the Islam is a monotheistic religion.
