Muhammad is best known as a Muslim prophet who received revelations from God through the angel Gabriel. The prophecies were revealed to Muhammad over a period of 23 years and are known as the Quran. His greatest achievement was founding the religion of Islam.
Muhammad was born in the year 570 in the Arabian city of Mecca. Although illiterate, he married a wealthy woman who was 15 years his senior. It was this wealthy marriage that gave Muhammad time to reflect on the problems facing his people. In Mecca at the time, there was general unrest. Politically, Muhammad created the framework that made the unification of the Arab tribes possible. This paved the way for the Arab Empire to grow and for the Islamic religion to expand beyond Mecca.
Muhammad was said to be a charming person who was tender and gentle with his people and is remembered as a visionary, administrator and statesman. Muhammad and his first wife had four daughters and several sons who died as infants. Upon his death, he had a total of nine wives and a concubine. Wikipedia
