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 opposed the rule of the third caliph in Islam, Uthman ibn Affan, but unlike the more extreme Kharijites the Ibadis rejected the murder of Uthman as well as the Kharijite belief that all Muslims holding differing viewpoints were infidels. 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.
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.
Relations with other communitiesEdit
Despite predating all Sunni and Shia schools by several decades, the Ibadis and their beliefs remain largely a mystery to outsiders, both non-Muslims and even 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 isolated nature of Oman granted the Ibadi denomination, secretive by nature, the perfect environment to develop in isolation from the Islamic mainstream. Ibadis were cut off even from the Kharijite sect because of Ibn Ibaḍ's criticism of their excesses and his rejection of their more extreme beliefs. The spread of Ibadism in Oman essentially represents the triumph of theology over tribal feudalism and conflict.
Ibadis have been referred to as tolerant Puritans or as political quietists because of their preference to solve differences through dignity and reason rather than with confrontation, as well as their tolerance for practising Christians, Hindus, Sikhs and Jews sharing their communities. Muscat, Oman presently has Churches, Temples, and Gurudwaras. 
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.
Doctrinal differences with other denominationsEdit
Ibāḍīs have several doctrinal differences with other denominations of Islam, chief among them:
- God will not show himself to Muslims on the Day of Judgment, a belief shared with Shias. Sunnis believe that Muslims will see God on the Day of Judgment.
- The Quran was created by God at a certain point in time. This belief is shared with the Mutazila, whereas Sunnīs hold the Quran to be co-eternal with God, as exemplified by the suffering of Ahmad ibn Hanbal during the miḥnah.
- Like the Mutazila and Shias, they interpret anthropomorphic references to God in the Qur'an symbolically rather than literally.
- Their views on predestination are like the Ashari Sunnis (i.e. occasionalism).
- It is unnecessary to have one leader for the entire Muslim world, and if no single leader is fit for the job, Muslim communities can rule themselves. That is different from both the Sunni belief of Caliphate and the Shia belief of Imamah.
- It is not necessary for the ruler of the Muslims to be descended from the Quraysh tribe, which was the tribe of the Muslim prophet Muhammad. That is different from Shias:7
- They believe it is acceptable to conceal one's beliefs under certain circumstances (kitman), analogous to the Shia taqiyya.
Views on Islamic history and caliphateEdit
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
Moroccan explorer Ibn Battuta observed Ibadis praying Jumu'ah in Oman and said they prayed in the same manner as Zuhr prayer. He noticed that they invoked God's mercy on Abu Bakr and Umar but not Uthman and Ali.
In their belief, the next legitimate caliph was Abdullah ibn Wahb al-Rasibi, the leader of the Kharijites who turned against Ali for his acceptance of arbitration with Muawiyah.:10 All Caliphs from Mu'āwīyah onward are considered tyrants except Umar ibn Abdul Aziz, on whom opinions differ. Numerous Ibāḍī leaders are recognized as true imams, including Abdullah ibn Yahya al-Kindi of South Arabia and the imams of the Rustamid dynasty in North Africa. Traditionally, conservative Omani Ibadism rejected monarchy and hereditary rule, and Ibadhi leaders were elected.
Despite bitter religious disputes elsewhere, the Ibadis are realists and believe that reason and political expediency must temper the ideal Islamic state.
View of hadithEdit
Ibadis accept as authentic far fewer hadith than do Sunnis. Several Ibadi founding figures were noted for their hadith research, and Jabir ibn Zayd is accepted as a reliable narrator even by Sunni scholars as well as by Ibadis. After the death of Ibn Ibad, Ibn Zayd led the Ibadis and withdrew to Oman, where his hadith, along with those of other early Ibadis formed the corpus of their interpretation of Islamic law.
View of theologyEdit
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 mainly.
View of jurisprudenceEdit
The fiqh or jurisprudence of Ibadis is relatively simple. Absolute authority is given to the Qur'an and hadith; new innovations accepted on the basis of qiyas, or analogical reasoning, were rejected as bid‘ah by the Ibadis. That differs from the majority of Sunnis (except minority Zahiri and early Hanbali schools of Sunnism) but agrees with Shias.
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. Ibadis are also found in East Africa (particularly Zanzibar), the Nafusa Mountains of Libya, and Djerba Island in Tunisia.
