Muhammad was orphaned at an early age, travelled as a caravan guide in his youth and had only one wife until he was 54. As a young adult, Muhammad became respected by older merchants he met in his travels.
Muhammad, who was born in 570, was raised by his mother until her death when he was 5 or 6. He then lived with his paternal grandfather until his death when Muhammad was 8. The future prophet was then placed in the care of his uncle in Mecca with whom he remained until adulthood.
Muhammad worked as a shepherd to earn his keep under his uncle's care. He traveled with caravans from Mecca to Syria with his uncle, and he met many people of many different faiths during these journeys. As a young man, Muhammad was given the nickname "El-Amin," the one you can trust.
In his early 20s, Muhammad was employed by a widow and wealthy merchant named Khadija bint Khawalayd. Muhammad worked carrying her goods north from Mecca to sell. At the age of 25, Muhammad married Khadija, who was 40 years old. The couple had six children, two sons who died in infancy and four daughters. Although polygamy was legal and socially acceptable, Muhammad remained married only to Khadija until her death 24 years later.
