Islam A to Z

Muhammad was born in 570, and died on June 8th, 632). He was a trader, later becoming a religious, political, and military leader. However, Muslims regard him as the last messenger of God, through which the Qur'an was revealed. Muslims view Muhammad as the restorer of the original uncorrupted monotheistic faith of Adam, Abraham, Moses, Jesus, and other prophets.

Revelations: For the last 22 years of his life, beginning at age 40 in 610 CE, Muhammad started receiving revelations that he believed to be from God. By 630 Muhammad was victorious in the nearly bloodless Conquest of Mecca, and by the time of his death in 632 (at the age of 63) he untied the tribes of Arabia into a single religious polity. In less than 50 years after the death of Muhammad, through conquest and conversion, Islam, shook the foundations of Byzantine and Persia, the 2 most powerful civilizations of the era. In less than a century Islam dominated an area larger than the Roman Empire at its peak.
Islamic Golden Age: The Abbasid historical period lasting to the Mongol conquest of Baghdad in 1258 CE is considered the Islamic Golden Age. During this period the Muslim world became an intellectual center for science, philosophy, medicine and education as the Abbasids championed the cause of knowledge and established the House of Wisdom in Baghdad. "In virtually every field of endeavor - in astronomy, alchemy, mathematics, medicine, optics and so forth - the Caliphate's scientists were in the forefront of scientific advance."
