Muhammad PBUM was the last prophet and founder of Islam.
Muhammad was born around 570, AD in Mecca (now in Saudi Arabia). His father died before he was born and he was raised first by his grandfather and then his uncle. He belonged to a poor but respectable family of the Quraysh tribe.
At age 40, he began to have revelations from Allah that became the basis for the Koran and the foundation of Islam. By 630 he had unified most of Arabia under a single religion. As of 2015, there are over 1.8 billion Muslims in the world who profess, “There is no God but Allah, and Muhammad PBUM is his prophet.”
