Family tree of Ali

Ali (Alī ibn Abī Ṭālib) (علي بن أﺑﻲ طالب) (599 – 661) was an early Islamic leader. He is revered by Sunni Muslims as the last of the four Rightly Guided Caliphs and as a foremost religious authority on the Qur'an and Fiqh (Islamic jurisprudence). Shi'a Muslims consider him the First Imam appointed by the Islamic prophet Muhammad and the first rightful caliph. Ali was the cousin of Muhammad, and after marriage to Fatimah he also became Muhammad's son-in-law.

His father was Abu Talib and his mother was Fatima bint Asad, but he was raised in the household of Muhammad, who himself was raised by Abu Talib, Muhammad's uncle and Ali's father. When Muhammad reported receiving a divine revelation, Ali was the first child to accept his message and first to convert to Islam at the age of 12, dedicating his life to the cause of Islam.

In Muslim culture, Ali is respected for his courage, knowledge, belief, honesty to Islam, deep loyalty to Muhammad, equal treatment of all Muslims and generosity in forgiving his defeated enemies, and therefore is central to mystical traditions in Islam such as Sufism. Ali retains his stature as an authority on Quranic exegesis, Islamic jurisprudence and religious thought. Ali holds a high position in almost all Sufi orders which trace their lineage through him to Muhammad. Ali's influence has been important throughout Islamic history.
