Ibadi

The Ibadi (Arabic: Al-Ibadhiyyah lbDy@) is a denomination of Islam that is the dominant form in only one country, Oman. There are other Ibadi in Algeria and Libya. The Ibadi probably started one of the earliest schools, which was founded less than 50 years after the death of Muhammad.
The name comes from Abdullah ibn Ibadh at-Tamini. Some of the branch's followers, however, claim that its true founder was Jabir ibn Zaid al-'Azdi, who was from Nizwa, Oman.
Differences from other types of Islam
Ibadi communities are generally seen as conservative. For example, they reject the practice of qunut in which one asks Allah for things while one stands in prayer. Sunni Muslims traditionally consider the Ibadi to be an extremist Kharijite group because they came from that group. However, most Ibadi now believe that other Muslims are not kuffar "unbelievers", unlike most Kharijite groups, but kuffar an-nima "unbelievers in God's grace." Most Ibadi now believe a true believer's attitude to others to be expressed in three religious obligations:
walayah: being friendly and united with practicing true believers and the Ibadi imans.
bara'ah: refusing to deal with unbelievers and sinners and showing a certain hostility towards them and those destined for Hell.
wuquf: being reserved towards those whose status is unclear.
Unlike the Kharijites, the Ibadi have abandoned the assassination of mainstream Muslims.
The Ibadi agree with Sunnis in approving of Caliphs Abu Bakr and Umar ibn al-Khattab, and both groups regarded them as rightly-guided caliphs. However, the Ibadi think that Uthman ibn Affan introduced bid'ah "innovations" to Islam and so approve of the revolt that overthrew him.
The Ibadi also approve of the first part of Ali's caliphate. Like the Shi'ites,the Ibadi disapprove of both Aisha's rebellion against him and Muawiya's revolt.
However, the Ibadi regard Ali's acceptance of arbitration at the Battle of Siffin against Muawiyya's rebels as un-Islamic. The Ibadi consider that Al's decision made him unfit as iman, and they condemn Ali also for killing early Kharijites in an-Nahr at the Battle of Nahrawan.
The Ibadi also have several doctrinal differences from other types of Islam; here are the main ones:
The Ibadi believe that Muslims will not see Allah on the Day of Judgement. That is derived from the Qur'an, which says Ibrahim/Abraham is told upon asking to see Allah, "You shall not see me. That is contrary to the mainstream Sunni belief that indeed, Muslims will see Allah with their eyes on the day of Judgment in a way and a manner that Allah knows best. That matches the beliefs of Shia Muslims: Imam Ali (AS) "Eyes can not see Him, but he can be seen by the realities of FAITH" Nahj al-Balaghah.
The Ibadi believe that whoever enter Hell will be there forever. That is contrary to the Sunni belief that Muslims who enter Hell will live there for a fixed amount of time to purify them of their shortcomings, and they will then enter Paradise. Sunnis also believe that unbelievers will remain in Hell forever.
The Ibadi believe that the Qur'an is created. The Sunnis hold vigorously that the Qur'an is uncreated, as exemplified by the suffering of Imam Ahmad ibn Hanbal. Many Shi'ites also hold that the Qur'an is created, which is one of many theological beliefs that they share with the Mu'tazilah of Iraq.
The Ibadi do not see the Sunni hadiths Kutub al-Sittah (or the Shia hadiths) as canonical but rely more on individual interpretations.
The Ibadi believe that the fifth legitimate caliph was Abdullah ibn Wahb al-Rasibi. All caliphs from Mu?awiyya onwards are regarded as tyrants except Umar ibn Abdul Aziz on whom opinions differ. However, various later Ibadi 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.
The Ibadi are also found in Jabal Nafusa in Libya, Mzab in Algeria, East Africa (particularly Zanzibar), and Djerba Island in Tunisia. The early medieval Rustamid dynasty in Algeria was Ibadi, and refugees from its capital, Tahert, founded the North African Ibadi communities, which still exist.
