Muhammad, the final Islamic prophet, was born and lived in Mecca for the first 52 years of his life (570–622 CE) until the Hijra. This period of his life is characterized by his proclamation of prophethood. Muhammad's father, Abdullah ibn Abd al-Muttalib, died before he was born. His mother would raise him until he was 6 years old, before her death around 577 CE at Abwa'. Subsequently raised by his grandfather, Abd al-Muttalib, and then his uncle, Abu Talib ibn ‘Abd al-Muttalib, Muhammad's early career involved being a shepherd and merchant. Muhammad married Khadija bint Khuwaylid after a successful trading endeavour in Syria. After the death of Khadija and Abu Talib in the Year of Sorrow, Muhammad married Sawda bint Zam'a and Aisha.
