The Ibadi movement, Ibadism or Ibāḍiyya, also known as the Ibadis (Arabic: الإباضية, al-Ibāḍiyyah), is a school of Islam dominant in Oman. It is also found in parts of Algeria, Tunisia, Libya and East Africa. The movement is said to have been founded around the year 650 CE or about 20 years after the death of the Islamic prophet Muhammad, predating both the Sunni and Shia denominations. Modern historians trace back the origins of the denomination to a moderate current of the Khawarij movement;:3 contemporary Ibāḍīs strongly object to being classified as Kharijites, although they recognize that their movement originated with the Kharijite secession of 657 CE.:3
The school derives its name from ʿAbdu l-Lāh ibn Ibāḍ of the Banu Tamim. Ibn Ibad was responsible for breaking off from the wider Kharijite movement roughly around the time that Abd al-Malik ibn Marwan, the fifth Umayyad ruler, took power.:11 However, the true founder was Jābir ibn Zayd of Nizwa, Oman.:12 Initially, Ibadi theology developed in Basra, Iraq. The Ibadis were among the more moderate groups opposed to the fourth caliph, Ali, and wanted to return Islam to its form prior to the conflict between Ali and Muawiyah I. They called themselves Muhakkima, Muhakkima (Arabic: محكمة) and al-Haruriyya (Arabic: الحرورية) refers to the Muslims who rejected arbitration between Ali ibn Abi Talib and Mu'awiya at the Battle of Siffin in 657 CE. The name Muḥakkima derives from their slogan la hukma illa li-llah, meaning "judgment (hukm) belongs to God alone". The name al-Haruriyya refers to their withdrawal from Ali's army to the village of Harura' near Kufa. This episode marked the start of the Kharijite movement, and the term muḥakkima is often also applied by extension to later Kharijites.
Due to their opposition to the Umayyad Caliphate, the Ibadis attempted an armed insurrection starting in the Hijaz region in the 740s. Caliph Marwan II led a 4,000 strong army and routed the Ibadis first in Mecca, then in Sana'a in Yemen, and finally surrounded them in Shibam in western Hadhramaut. Problems back in their heartland of Syria forced the Umayyads to sign a peace accord with the Ibadis, and the sect was allowed to retain a community in Shibam for the next four centuries while still paying taxes to Ibadi authorities in Oman. For a period after Marwan II's death, Jabir ibn Zayd maintained a friendship with Umayyad general Al-Hajjaj ibn Yusuf, who supported the Ibadis as a counterbalance to more extreme Kharijites. Ibn Zayd ordered the assassination of one of Al-Hajjaj's spies, however, and in reaction many Ibadis were imprisoned or exiled to Oman.:12[dubious ]
It was during the 8th century that the Ibadis established an imamate in the inner region of Oman. The position was an elected one, as opposed to Sunni and Shi'a dynasties where rule was inherited. These imams exerted political, spiritual and military functions.
By the year 900, Ibadism had spread to Sind, Khorosan, Hadhramaut, Dhofar, Oman proper, Muscat, the Nafusa Mountains, and Qeshm; by 1200, the sect was present in Al-Andalus, Sicily, M'zab (the Algerian Sahara), and the western part of the Sahel region as well. The last Ibadis of Shibam were expelled by the Sulayhid dynasty in the 12th century. In the 14th century, historian Ibn Khaldun made reference to vestiges of Ibadi influence in Hadhramaut, though the sect no longer exists in the region today.

Ibadis state, with reason, that their school predates that of mainstream Islamic schools, and Ibadism is thus considered to be an early and highly orthodox interpretation of Islam.
Ibadi imamate and political theory
Unlike the Sunni theory of the caliphate and the Shi'a notion of divinely appointed Imamate, the leaders of Ibadi Islam—called Imams—do not need to rule the entire Muslim world; Muslim communities are considered capable of ruling themselves. The Ibadis reject the belief, shared by Sunnis and Shi'as alike, that the leader of the Muslim community must be descended from the Quraysh tribe. Rather, the two primary qualifications of an Ibadi imam are that he is the most pious man of the community and the most learned in fiqh, or Islamic jurisprudence; and that he has the military knowledge to defend the Ibadi community against war and oppression. In the Omani tradition, an imam who is learned in the Islamic legal sciences is considered "strong" (qawī), and an imam whose primary skills are military without scholarly qualifications is considered "weak" (ḍaʻīf). Unlike a strong imam, a weak imam is obliged to consult the ulamāʾ, or community of scholars, before passing any judgement. A weak imam is appointed only at times of dire necessity, when the community is threatened with destruction.:137
Contemporary Ibadis uphold four "states of the religion" (masālik ad-dīn), which are four different types of imams each appropriate to certain contexts. The imām al-kitmān "Imam of secrecy" is a learned scholar who "rules" in political quietism, practicing taqiyya to avoid persecution, in times when the Ibadi community cannot reveal itself openly.:13 In some cases, a state of kitmān may be necessary even when there is no imam available. In this case, the Ibadi ulamāʾ takes over as surrogate rulers in place of the imam. This has been the case for most of the history of the North African Ibadis since the fall of the Rustumid imamate in 909,:76 unlike their Omani coreligionists, who periodically reestablished imamates until 1958.:10
The second state, that of the imām al-shārī "Imam of exchange", are Ibadi imams who "exchange" their lives in the living world for a favorable place in the afterlife by engaging in military struggle (jihād) against an unbearable tyrannical authority with the goal of creating an Ibadi state.:13–14 A would-be imām al-shārī cannot begin military action until they have found at least forty followers willing to die for the cause; once the war has begun, the imam must continue to fight until there are only three followers remaining. A particularly ascetic lifestyle is required of the imām al-shārī and his followers, as suggested in the following advice::107
You go out to fight in the way of God desiring His pleasure, not wanting anything of the goods of the present world, nor have you any desire for it, nor will you return to it. You are the ascetic and the hater of this life, desirous of the world to come, trying with all in your power to obtain it: going out to be killed and for nothing else. So know that you are [already] killed and have no return to this life; you are going forward and will not turn away from righteousness till you come to God. If such is your concern, go back and finish up your needs and wishes for this life, pay your debts, purchase yourself, take leave of your family and tell them that you will never return to them.
The third state, that of the imām al-zuhūr "Imam of glory", are imams as active rulers of an Ibadi state. The first two caliphs Abu Bakr and Umar are considered ideal models of the imām al-zuhūr. A ruling imam who sins must be removed from power; the Ibadi model for this is the assassination of the third caliph Uthman and the Kharijite revolt against Ali, both actions being viewed as legitimate resistance to a sinful ruler.:46
Finally, the state of the imām al-difā' "imam of defense" involves appointing an imam for a predetermined period of time when the Ibadi community is under foreign attack. He is removed once the threat has been defeated.:137
Views of other denominations
Ibadis believe that only righteous Ibadis, referred to as the ahl al-istiqāmah "people of straightness", are worthy of being called "Muslims". Non-Ibadi Muslims are termed the ahl al-khilaf "people of opposition". Nonetheless, non-Ibadi Muslims are still respected as fellow members of the ummah or wider Islamic community, who possess the various privileges accorded to Muslims in Islamic law and who Ibadis may intermarry with.:28 All non-Ibadi Muslims and even Ibadi sinners are considered guilty of kufr (usually translated as "unbelief"), although contemporary Ibadis distinguish between kufr shirk, or religious disbelief, and kufr nifaq, or infidelity in the form of sinning. The term shirk—"polytheism" in conventional Islamic theology—has a wider use in Ibadi doctrine, where it is used to describe all forms of religious error beyond polytheism alone.:28
Classical Ibadi theologians have stated that only the ahl al-istiqāmah will go to paradise, and that all sinning Ibadis as well as all non-Ibadis will burn in hell forever. Ibadis traditionally reject Sunni beliefs that all Muslims in hell will eventually enter paradise, and hold that hell is eternal and inescapable for all humans who were not righteous Ibadis in life.:30
The notions of walaya "affiliation" and bara'a "disassociation" are central to the theology of Ibadi relations with non-Ibadi people. Only righteous Ibadis are considered worthy of friendship and association, whereas sinners and non-Ibadi Muslims are subject to dissociation, sometimes to the point of ostracism.:29 Modern Ibadi scholars suggest that the duty of dissociation does not require rudeness or social avoidance, and that an Ibadi may have genuine affection for a non-Ibadi; nonetheless, "an inner awareness of separation" between upright Ibadis and non-Ibadis must be maintained.:29 In practice, however, Ibadi Muslims have generally been very tolerant of non-Ibadi religious practice.:29 During the period of imām al-kitmān, the duties of affiliation and disassociation are no longer valid.:43
Ibadi beliefs remain understudied by outsiders, both non-Muslims and other Muslims.:3 Ibadis have claimed, with justification, that while they read the works of both Sunnis and Shias, even the learned scholars of those two sects never read Ibadi works and often repeat myths and false information when they address the topic of Ibadism without performing proper research.:4
The development of Ibadi theology happened thanks to the works of scholars and imams of the community, whose histories, lives, and personalities are part of the Islamic history. Ibāḍī theology can be understood on the basis of their works Ibn Ibāḍ, Jābir bin Zayd, Abū ‘Ubaida, Rabī‘ b. Ḥabīb and Abū Sufyān among others. Basra is the foundation of the Ibāḍī community. Various Ibāḍī communities that were established in southern Arabia, with bases in Oman, North Africa, and East Africa.
In terms of scholastic theology, the Ibadi creed resembles that of the Muʿtazila in many aspects, except in the central question of predestination.:34 Like the Muʿtazila and unlike the modern Sunni, the Ibadis believe that:
- Human knowledge of God is innate through the use of reason, rather than being learned. Therefore, a Quranic verse that appears to contradict with human reason must be metaphorically reinterpreted in the light of reason rather than being taken as fact. It is forbidden to decide matters of religious belief by taqlid, or deference to a clerical or otherwise human authority.:36–37
- The attributes of God are not distinct from his essence. Mercy, power, wisdom, and other divine attributes are merely different ways to describe the single unitary essence of God, rather than independent attributes and qualities that God possesses.:37–38
- The Quran was created by God at a certain point in time. While Ibadis uphold the fact that "essential speech" is a way to describe his essence, they do not believe that the Quran is identical to this essence. The Quran is simply a created indicator of his essence. Sunnis believe that the Quran has always existed.:40–41
- They interpret anthropomorphic references to God in the Quran symbolically rather than literally. Therefore, God does not actually have hands, a face, a throne, or other physical attributes, as he cannot be perceived by human senses and has no physical reality.:36 They thus believe that Muslims will not see God on the Day of Resurrection, a belief shared with the Shi'a but not the Sunni. Similarly, Ibadis hold that the Scale on which God judges human deeds is metaphoric, as actions cannot be weighed.:36
But unlike the Muʿtazila, Ibadis follow the Ash'ari position of occasionalism, which holds that all events are caused directly by God and that what appear to be laws of causation, such as that a fire produces smoke, is only because God chooses to create fire, and then to create smoke. One Ibadi scholar has even stated that this single difference means that the Muʿtazila are more misguided than the Sunni.:34–35
The fiqh or jurisprudence of Ibadis is based on the same fundamental principles as Sunni and Shi'a juristic traditions, but the Ibadis reject taqlid or deference and stress the importance of ijtihad, or independent reasoning. Contemporary Ibadis hold that believers are allowed to follow incorrect opinions derived through ijtihad as long as they believe it to be true after having made an effort to arrive at the correct opinion; certain now-extinct Ibadi sects once held that those with incorrect opinions were disbelievers.:41–42 Many early Ibadis rejected qiyas or deductive analogical reasoning as a basis for jurisprudence, but the importance of analogies is now widely accepted by Ibadi jurists.:42
Ibadis believe that the stage of the imām al-kitmān corresponds to Muhammad's life in Mecca before the hegira, when no independent Muslim community existed that could enforce Islamic laws. Therefore, ḥudūd punishments are suspended under an imām al-kitmān, except the punishments for apostasy, blasphemy, and murder. Ibadis also do not hold Friday prayers in the absence of a legitimate ruling imam.:43
The Ibadis differ from Sunnis on certain issues of law. They have a legally fixed amount of diya (compensation to the victim in case of crime), rather than permitting negotiation between the parties. Like the Shi'a but unlike the Sunni, Ibadis allow a man to be executed as qiṣāṣ (retributive justice) for the murder of a woman, so long as the victim's family pays the man's family half of the diya that would have been incumbent had they murdered the man. Also like the Shi'a but not the Sunni, they do not allow a couple who has committed zināʾ (unlawful sex) to marry each other.:44
During the Ramadan fast, Ibadis require ghusl or full-body ablution every morning. They hold that committing grave sins is a form of breaking the fast. When making up for missed days of fasting after Ramadan has ended, the Ibadis believe that the atonement fast must be consecutive, whereas both Sunnis and Shi'as believe that Muslims may atone for missed days by fasting for the required amount at any time, whether consecutive or nonconsecutive.:44
Like the Shi'a and some Maliki Sunnis, the Ibadis keep their arms at their sides rather than clasping the hands during prayer. During the noon and afternoon prayers, Ibadis recite solely al-Fātiḥah, the first chapter of the Quran, whereas other Muslims may recite other Quranic verses in addition. They also do not say ʾāmīn after the recitation of al-Fātiḥah. Ibadis shorten prayers when staying in foreign territory—even if they do so on a permanent basis—unless they choose to adopt the country as their new homeland; Sunnis generally hold that believers should return to the full prayer after a given number of days outside of home.:43
The primary Ibadi collection of hadiths, or traditions and sayings attributed to the prophet Muhammad, is the twelfth-century Tartīb al-Musnad, comprising 1,005 hadiths.:231 The Tartīb is divided into four books. The first two books are muttaṣil narrations by Jabir ibn Zayd, a student of Muhammad's widow Aisha. The third book includes hadith transmitted by the eighth-century Kharijite scholar al-Rabi' bin Habib Al-Farahidi as preserved in the Jami Sahih collection, generally also from Jabir ibn Zayd. The fourth book consists of an appendix of saying and stories from later Ibadi scholars and imams.:232–233
Most of the Ibadi hadiths have a very short isnād or chain of transmission. They are claimed to be narrated from Jabir ibn Zayd to his student Abu Ubayda Muslim ibn Abi Karima and from the latter to al-Rabi', who died in 786 after preserving his transmissions in the Jami Sahih. This was then reformulated into the Tartīb al-Musnad some four centuries later. The non-Muslim scholar J. C. Wilkinson states that this chain of transmission "does not stand up to any close examination". It may be a fabrication to buttress the strength of the Ibadi school by making the Ibadis have the oldest collection of hadiths; the Sunni Kutub al-Sittah collections are both from the mid-ninth century, and the Shi'a Kitab al-Kafi is from the tenth century.:234 Most Ibadi hadiths are found in the standard Sunni collections, bar a small group with Kharijite biases,:233 and contemporary Ibadis often approve of the standard Sunni collections.:3–4
Unlike in Sunni and Shi'a Islam alike, the study of hadiths has not traditionally been very important in Ibadi Islam, especially in Oman where Sunni influence was weaker.:239
Views on early Islamic history
Ibadis agree with Sunnis, regarding Abu Bakr and Umar ibn al-Khattab as rightly-guided caliphs.:7 They regard the first half of Uthman ibn Affan's rule as righteous and the second half as corrupt and affected by both nepotism and heresy.:7 They approve of the first part of Ali's caliphate and (like Shī'a) disapprove of Aisha's rebellion and Muawiyah I's revolt. However, they regard Ali's acceptance of arbitration at the Battle of Ṣiffīn as rendering him unfit for leadership, and condemn him for killing the Khawarij of an-Nahr in the Battle of Nahrawan. Modern Ibadi theologians defend the early Kharijite opposition to Uthman, Ali and Muawiyah.:10
In their belief, the next legitimate caliph and first Ibadi imam was Abdullah ibn Wahb al-Rasibi, the leader of the Kharijites who turned against Ali for his acceptance of arbitration with Muawiyah and was killed by Ali at Nahrawan.:10 Ibadis believe that the "genealogy of Islam" (nasab al-islām) was transmitted by other individuals at Nahrawan, such as Ḥurḳūṣ ibn Zuhayr al-Saʿdī, and developed into Ibadi Islam, the true form of the faith.:43
The Wahbi is considered to be the most mainstream of the schools of thought within Ibadism.  The main reason why the Wahbi strain has come to dominate within Ibadism is that most textual references that have been preserved can be attributed to Wahbi affiliated scholars.
The dating of early writings such as kutub al-rudud and siras (letters) written by Ibadis has led some analysts such as Salim al-Harithi to claim Ibadism as the oldest sect within Islam. However others suggest Ibadism only took on characteristics of a sect and a full-fledged madhab during the demise of the Rustamid Imamate.
The term Wahbi is chiefly derived as an eponymous intimation to the teachings of Abdullah bin Wahb al-Rasibi. Although the term Wahbi was initially considered superfluous as Ibadism was largely homogenous, its usage increased upon the advent of the Nukkari secession in order to differentiate the Wahbis from the off-shoot Ibadis. The most common epithet Wahbi Ibadi clerics enjoined their adherents to apply to themselves is the term ahl al istiqama meaning those on the straight path. They rejected the usage of ahl al -sunnah as early usage assigned the term sunnah as the practise of Muawiyah cursing Ali ibn Abi Talib from the pulpits, although during the Ummayad era, this meaning changed.
Ibadis make up a majority (roughly 75%) of the population in Oman. There are roughly 2.72 million Ibadis worldwide, of which 250,000 live outside Oman. As a result, Oman is the only country in the Muslim world with an Ibadi-majority population.
Historically, the early medieval Rustamid dynasty in Algeria was Ibadi, and refugees from its capital, Tiaret, founded the North African Ibadi communities, which still exist in M'zab. The Mozabites, a Berber ethnic group in M'zab, are Ibadis. Ibadism also exists elsewhere in Africa, particularly in Zanzibar in Tanzania, the Nafusa Mountains in Libya, Djerba Island in Tunisia, and among the Dishiishe clan of Somalis.
