When he was roughly forty, Muhammad began having visions and hearing voices.

After working for several years as a merchant, Muhammad was hired by Khadija, a wealthy widow, to ensure the safe passage of her caravans to Syria. Mecca was home to two widely venerated polytheistic cults whose gods were thought to protect its lucrative trade. Several trade routes intersected at Mecca, allowing the Quraish to control trade along the west coast of Arabia, north to Syria, and south to Yemen. Muhammad was born into the most powerful tribe in Mecca, the Quraish, around 570 A.D. The power of the Quraish derived from their role as successful merchants. After the holy Qur'an, the sayings of the Prophet ( hadith) and descriptions of his way of life ( sunna) are the most important Muslim texts. Because Muhammad was the chosen recipient and messenger of the word of God through the divine revelations, Muslims from all walks of life strive to follow his example. The rise of Islam is intrinsically linked with the Prophet Muhammad, believed by Muslims to be the last in a long line of prophets that includes Moses and Jesus.
