Mohammed was born in Mecca in 570 CE. He was orphaned early in his life and was raised by his uncle. Mohammed worked in his uncle's business and quickly established a reputation as a highly honest person. At the age of twenty he was hired by a wealthy widow named Khadija to manage her late-husband's caravan business. When Mohammed was 25, Khadija proposed marriage and Mohammed accepted. Although several children were born to them, only one survived into adulthood, their daughter Fatima . In 610, Mohammed sought out and began to have visions from Allah . Through the angel Gabriel , Allah transmitted the entire Koran to Mohammed. When Mohammed began to preach his new religion, the rulers of Mecca were strongly opposed. In 622, Mohammed was approached by the elders of a town some 250 miles to the north and asked to be their ruler. Mohammed accepted on the conditions that they would also accept him as a prophet and that he could bring his followers. The exodus to this town, Medina as it later came to be known, was called the hijra . The Meccans attacked the Medinans several times, but the Medinans always managed to drive them off. In 630, the Meccans were defeated by Mohammed's forces and the Moslems returned to Mecca to rule there and cleanse the Kaba of all its idols. Mohammed continued to rule Medina, where he died in 632. Islam considers Mohammed the last of a long line of prophets of Allah and has given him the title of the Seal of the Prophets .
