Explanation

He was an uncle of the Islamic prophet Muhammad, and the father of Ali.

Abu Talib died around 619 AD, at more than 80 years of age, about 10 years after the start of Muhammad's mission (نبوت).

This year is known as the Year of Sorrow for Muhammad, because not only did his uncle Abu Talib die, but also his wife Khadijah bint Khuwaylid, within a month of Abu Talib.

After Abu Talib's death, Muhammad was left unprotected.
