In Muslim tradition, Muhammad is viewed as the last in a series of prophets. For the last 22 years of his life, beginning at age 40 in 610 CE, Muhammad started receiving revelations from God. The content of these revelations, known as the Qur'an, was memorized and recorded by his companions. During this time, Muhammad preached to the people of Mecca, imploring them to abandon polytheism. Although some converted to Islam, Muhammad and his followers were persecuted by the leading Meccan authorities. After 12 years of preaching, Muhammad and the Muslims performed the Hijra ("emigration") to the city of Medina in 622. There, with the Medinan converts and the Meccan migrants, Muhammad established his political and religious authority. Within years, two battles had been fought against Meccan forces: the Battle of Badr in 624, which was a Muslim victory, and the Battle of Uhud in 625, which ended inconclusively
