Kharijites

Lore & Background

The Kharijites were an early Islamic sect that first appeared during the First Fitna. They were originally supporters of Ali who turned against him when he agreed to arbitration with his rival Mu'awiya after the Battle of Siffin. Their central motto was "judgment belongs to God alone," and they held that rebels such as Mu'awiya must be fought in accordance with Qur'anic commands. Ali defeated them at the Battle of Nahrawan, but their insurgency persisted, and a Kharijite later assassinated Ali. Under the Umayyad Caliphate, governors generally kept them in check until the power vacuum of the Second Fitna allowed factions like the Azariqa and Najdat to seize large areas in Persia and Arabia. Internal fragmentation weakened these groups before Umayyad forces defeated them. Further large-scale revolts erupted in the 740s but were suppressed, and militant Kharijite groups were gradually eliminated under the Abbasids, replaced by the non-activist Ibadiyya, who survive today in Oman and parts of North Africa but reject any connection to earlier Kharijites. The Kharijites lacked a uniform doctrine: they believed any morally irreproachable Muslim could be caliph, regardless of descent, and that sinful caliphs must be rebelled against and deposed. Most groups branded Muslims who committed grave sins as disbelievers, and the most militant considered killing such unbelievers lawful unless they repented. Many Kharijites were skilled orators and poets, with piety and martyrdom as major poetic themes. They also participated in theological debates, influencing mainstream Islamic thought. Almost no primary Kharijite sources survive; what is known comes from later, hostile non-Kharijite histories and heresiographical works, making their true motives difficult to ascertain.

Reader's Guide

The Kharijites are significant for their radical theology and political activism in early Islam. They held that any Muslim, regardless of descent, could be caliph if morally irreproachable, and that sinful caliphs must be deposed. Most Kharijite groups considered Muslims who committed grave sins to be disbelievers, and the most militant deemed killing such unbelievers licit unless they repented. Their poetry emphasized piety and martyrdom. In the eighth and ninth centuries, they participated in theological debates that influenced mainstream Islamic theology. Modern mainstream Muslims often use the term 'Kharijites' to describe Islamist extremist groups, while some Arab historians stress their egalitarian and proto-democratic tendencies. Academic historians are divided on whether the movement was driven by religious, economic, or Bedouin challenges to state organization. The surviving Ibadiyya sect rejects any connection to the early Kharijites.

Did You Know?

• The term 'Kharijites' comes from the Arabic root meaning 'to leave' or 'to go out,' used by opponents for leaving Ali's army.
• The Ibadiyya, the only surviving Kharijite-related sect, condemns early Kharijites as extremists and denies any link to them.

Origins in the First Fitna

Their revolt was triggered by Ali's decision to accept arbitration talks with his rival Mu'awiya rather than press the military confrontation. The group coalesced around the principle that judgment belongs to God alone, which became their defining motto, and they insisted that rebels such as Mu'awiya must be fought and overcome in accordance with Qur'anic injunctions. This compressed sequence—arbitration, open revolt, military defeat, and regicide—established the Kharijites as a recurring force in Islamic political history, one that would resurface repeatedly over the following centuries.

Centuries of Rebellion and Gradual Decline

During this window, the Kharijite sub-factions known as the Azariqa and the Najdat seized control over substantial territories in both Persia and Arabia. Over time the most militant groups were eliminated and succeeded by the non-activist Ibadiyya, a community that endures today in Oman and parts of North Africa. The Ibadis, however, explicitly disavow any connection to the militant Kharijites of the early civil wars, condemning them as extremists.

Theology, Ethics, and Cultural Expression

The Kharijites never possessed a single, unified doctrinal code, yet several convictions were broadly shared across their factions. They held that any Muslim, regardless of lineage or ethnic background, was eligible for the caliphate so long as he was morally unimpeachable. Equally central was the conviction that all Muslims bore a duty to rise against and depose any caliph who committed serious sin. Most Kharijite groups went further, declaring that a Muslim who had committed a grave transgression was no longer a believer but a disbeliever, and the most radical factions considered killing such individuals permissible unless they repented. Beyond theology, the Kharijites were noted for their eloquence in oratory and poetry, with piety and martyrdom serving as the dominant themes in their verse. In the eighth and ninth centuries, Kharijite thinkers engaged in formal theological debates and, in doing so, contributed ideas that helped shape mainstream Islamic theological discourse.

The Problem of Sources and Modern Interpretations

Reconstructing Kharijite history is complicated by the near-total absence of primary sources from within the movement itself. What survives comes overwhelmingly from non-Kharijite authors writing in the ninth and tenth centuries, and these sources are openly hostile. They fall into two broad categories: general histories and heresiographical works, both composed long after the events they describe and through the lens of an established orthodoxy. Heresiographers, working from a hadith predicting seventy-three sects in Islam with only one saved, were primarily interested in cataloguing deviant groups, sometimes altering or even inventing doctrines to fit classification schemes. The term Kharijite itself was an exonym, derived from the Arabic root meaning to leave or go out, referring to their departure from Ali's army. They called themselves al-Shurat, the Exchangers, interpreting this as those who traded worldly life for the life with God. Modern scholarship remains divided: some emphasize the group's egalitarian and proto-democratic impulses, others attribute their rise to economic pressures or nomadic challenges to state authority, and some reject the traditional Siffin origin story altogether.
