I am an angel sent from god, I am making you a prophet,a direct messenger from god for the rest of your life.
Later that day after the angel told Muhammad about Allah, he went to the town to tell the citizens of Mecca...
We need to follow god, not plural, god. Allah, THE god, says that all the people, rich and poor, should be equal.
That sounds insane! No one will believe you.
Not many people believed or followed Muhammad, so he left mecca and went to Medina with his few followers. He and his followers grew the Islamic culture and religion. The people that are still in Mecca started fighting with the rebellious people of Medina. Mecca eventually gave in.
