Imam Ali ibn Abi Talib — Life, Character and Legacy
The Prophet's cousin, ward and son-in-law: warrior, judge, caliph, and the author of Islam's finest writing on justice.

Ali ibn Abi Talib was born in Makkah around 600 CE, reportedly within the precinct of the Ka'bah, and raised in the Prophet's own household. He was the first youth to accept Islam and the man the Prophet called "my brother in this world and the next."
The years of struggle
He slept in the Prophet's bed on the night of the Hijrah while assassins surrounded the house. He carried the standard at Badr, held the line at Uhud, and at Khaybar was given the banner after the Prophet said he would hand it to "one who loves God and His Messenger and whom they love." At Tabuk the Prophet left him over Madinah with the words: "Are you not content to be to me as Harun was to Musa, except that there is no prophet after me?"
The scholar and judge
The Prophet said, "I am the city of knowledge and Ali is its gate." Umar ibn al-Khattab's repeated remark — "were it not for Ali, Umar would have perished" — is recorded in Sunni sources over the difficulty of legal cases. Ali structured Arabic grammar's foundations with Abu al-Aswad al-Du'ali, judged with famous precision, and formulated principles of evidence.
The caliph
He accepted the caliphate in 35 AH over a community already fractured by the killing of Uthman. He refused to distribute public wealth as political payment, dismissed corrupt governors, and consequently faced the Battle of the Camel, Siffin, and the Khawarij at Nahrawan. His letter appointing Malik al-Ashtar over Egypt — instructing him that the people are "either your brother in faith or your equal in creation" — is studied today as a charter of just administration and has been cited by the United Nations Development Programme as a model of governance.
The character
He owned little, patched his own sandals, fed orphans, and was assassinated by Ibn Muljam while praying in the mosque of Kufa in Ramadan 40 AH. His dying instruction to his sons was to fear God, protect orphans, and never abandon justice — and to give his killer only the punishment due, no more.
Legacy
For Shia Muslims he is the first Imam and designated successor. For Sunni Muslims he is the fourth rightly guided caliph and the greatest of judges. Sufi orders trace almost all their chains to him. Nahj al-Balagha remains a landmark of Arabic prose.
