Ali: The 4th Caliph of the Rashidun Caliphate
Ali ibn Abi Talib was the cousin and son-in-law of the Islamic prophet Muhammad (S.A.W), the fourth Rashidun caliph (656–661 CE), and the first Shia imam.
Early Life and Family
Ali ibn Abi Talib was born in Mecca around 600 CE to Abu Talib and Fatima bint Asad. His father, Abu Talib, was a prominent leader of the Banu Hashim clan within the Quraysh tribe.
Due to financial hardships, Muhammad, his elder cousin, took Ali into his household at a young age. Raised under Muhammad’s guidance, Ali developed strong moral and religious principles.
Ali was among the first to embrace Islam, making his declaration either second only to Khadija, Muhammad’s wife, or closely following Abu Bakr.

Role in Early Islam and Companionship of Muhammad
Ali played a critical role in the early years of Islam, standing steadfastly by Muhammad amid persecution in Mecca. During the emigration (Hijra) to Medina in 622, Ali acted as Muhammad’s decoy, risking his life to ensure Muhammad’s safe escape.
In Medina, Muhammad paired Muslims into brotherhood pacts, selecting Ali as his own brother. Ali married Muhammad’s daughter Fatima, strengthening his ties to the prophet.
Throughout Muhammad’s prophethood, Ali served as his secretary and flag bearer. He played significant roles in several battles, including Badr (624), Uhud (625), Khaybar (628), and Hunayn (630), earning a reputation for bravery. At the Battle of Khaybar, his courage reportedly led to the conquest of a critical fortress.
Ali was also present at the Treaty of Hudaybiyyah in 628 and was chosen by Muhammad to deliver an important Quranic announcement in Mecca.
Ghadir Khumm and Succession Dispute
One of the most debated moments in Islamic history occurred in 632 at Ghadir Khumm, where Muhammad is recorded as stating, “Whoever I am his mawla, this Ali is his mawla.” Shia Muslims interpret mawla as leader and successor, while Sunni Muslims see it as an affirmation of friendship and support. This statement remains at the heart of sectarian divides over leadership in Islam.
Following Muhammad’s death, a faction of Muslims gathered at Saqifa and appointed Abu Bakr as the first caliph, bypassing Ali. Ali did not immediately pledge allegiance, instead focusing on compiling the Quran. Eventually, after the death of his wife Fatima, Ali formally recognized Abu Bakr’s leadership.
Succession Following the Death of the Islamic Prophet Muhammad
Ali Under Rashidun Caliphs
During Abu Bakr and Umar’s caliphates, Ali acted as an advisor, though he often disagreed with their policies. His stance on Islamic governance was rigidly based on justice and Quranic principles.
When the second caliph, Umar, was assassinated, Ali was considered for the caliphate, but Uthman was chosen instead. Ali was critical of Uthman’s administration, particularly its nepotism, though he acted as a mediator during conflicts that led to Uthman’s assassination in 656.

Caliphate of Ali (656-661 CE)
After Uthman’s assassination, Ali was elected as the fourth caliph. His rule was immediately contested, leading to civil wars. His policies focused on justice and equality, which alienated influential figures accustomed to privileges. Ali dismissed many of Uthman’s governors, leading to opposition from provincial leaders like Mu’awiya in Syria.
Battle of the Camel (656 CE)
Ali faced a rebellion led by Aisha, Talha, and Zubayr, who demanded justice for Uthman’s murder. This culminated in the Battle of the Camel, where Ali’s forces emerged victorious. He forgave the defeated rebels and sent Aisha back to Medina with dignity.
Battle of Siffin (657 CE) and Arbitration
Ali’s biggest challenge came from Mu’awiya, the governor of Syria. The inconclusive Battle of Siffin led to an arbitration process, which weakened Ali’s position. A faction within Ali’s camp, the Kharijites, rejected the arbitration and later rebelled against him.
Battle of Nahrawan (658 CE)
Ali crushed the Kharijite revolt at the Battle of Nahrawan, but this victory came at a cost—many of his former supporters abandoned him, and his authority weakened.
Assassination of Ali
Ali was assassinated in 661 by a Kharijite named Ibn Muljam while praying at the Great Mosque of Kufa. His assassination paved the way for Mu’awiya to establish the Umayyad Caliphate.
Ali ibn Abi Talib remains a central figure in Islamic history, embodying the virtues of courage, justice, and devotion.
Ali is venerated for his wisdom, justice, and valor. Sunni Muslims regard him as the fourth and final Rashidun caliph, while Shia Muslims honor him as the first Imam. His teachings are collected in Nahj al-Balagha, and his shrine in Najaf remains a major pilgrimage site.
