Ibadi Islam in the context of "Islamic schools and branches"

Islamic schools and branches have different understandings of Islam. There are many different sects or denominations, schools of Islamic jurisprudence, and schools of Islamic theology, or ʿaqīdah (creed). Within Sunnī Islam, there may be differences, such as different orders (tariqa) within Sufism, different schools of theology (Atharī, Ashʿarī, Māturīdī) and jurisprudence (Ḥanafī, Mālikī, Shāfiʿī, Ḥanbalī). Groups in Islam may be numerous (Sunnīs make up 87-90% of all Muslims), or relatively small in size (Ibadis, Ismāʿīlīs, Zaydīs).

Differences between the groups may not be well known to Muslims outside of scholarly circles, or may have induced enough passion to have resulted in political and religious violence (Barelvism, Deobandism, Salafism, Wahhabism). There are informal movements driven by ideas (such as Islamic modernism and Islamism), as well as organized groups with governing bodies (such as Nation of Islam). Some of the Islamic sects and groups regard certain others as deviant or not being truly Muslim (for example, Sunnīs frequently discriminate against Ahmadiyya, Alawites, Quranists, and sometimes Shīʿas). Some Islamic sects and groups date back to the early history of Islam between the 7th and 9th centuries CE (Kharijites, Mu'tazila, Sunnīs, Shīʿas), whereas others have arisen much more recently (Islamic neo-traditionalism, liberalism and progressivism, Islamic modernism, Salafism and Wahhabism), or even in the 20th century (Nation of Islam). Still others were influential historically, but are no longer in existence (non-Ibadi Kharijites and Murji'ah).

Muslims, including Shia, Sunni, Ibadi and other branches, agree on two holiest sites in Islam being the Masjid al-Haram (including the Kaaba) in Mecca; the Masjid an-Nabawi in Medina.

Sites associated with the Islamic prophet Muhammad, his daughter Fatima and son-in-law Ali, the respective Shia Imams descended from them and their family members (collectively referred to as Ahl al-Bayt) are considered holy by the different Shia Muslim sects. Karbala and Najaf in Iraq are two of holiest cities revered by all Shia sects. Additionally, Mashhad and Qom in Iran are two of the holiest cities to Twelver Shia, the largest Shia sect.

The Imamate of Oman (Arabic: إِمَامَة عُمَان, romanised: Imāmat ʿUmān) was several succession of states within the Oman proper (Arabic: عُمَان ٱلْوُسْطَى, romanised: ʿUmān al-Wusṭā, lit. 'Central Oman') in the Hajar Mountains, part of the present-day Sultanate of Oman. The capital of the Imamate alternated historically between Rustaq and Nizwa. The Imamate's territory extended north to Ibri and south to the Alsharqiyah region and the Sharqiya Sands. The Imamate was bounded in the east by the Hajar Mountains and in the west by the Rub' al Khali (Empty Quarter) desert. The Al Hajar Mountains separated the Imamate of Oman from Muscat and Oman. The elected Imam (ruler) resided in the capital, and Walis (governors) represented the Imamate in its different regions.

The Imamate of Oman, similar to the Sultanate of Muscat, was ruled by the Ibadi sect. Imams exercised spiritual and temporal representation over the region. The Imamate is a 1,200-year-old system of government pioneered by the Ibadi religious leaders of Oman, and was based upon the Islamic sharia. The Imamate holds that the ruler should be elected. The imam is considered as the head of the community but tribalism that is part of the Omani society encouraged a decentralised form of governance that would help sustain political unity among the Omanis. The Imamate set out a government system wherein the ruler should not have absolute political nor military power; rather power should be shared with local governors. To prevent local or external threats to the Imamate, the imam had to gather the support of the local communities and tribes to raise a force to fight for a certain cause. The imam needed in-depth understanding of tribal politics and political acumen to maintain political stability within the Imamate when conflicts occurred.

Islam is the majority and state religion in Algeria. The vast majority of citizens are Sunni Muslims belonging to Maliki school of jurisprudence, with a minority of Ibadi Muslims, most of whom live in the M'zab Valley region. Islam provides the society with its central social and cultural identity and gives most individuals their basic ethical and attitudinal orientation. Orthodox observance of the faith is much less widespread and steadfast than is identification with Islam. There are also Sufi philosophies which arose as a reaction to theoretical perspectives of some scholars.

The Mozabite people or Banu Mzab (Arabic: بني مزاب, romanized: Banī Mzāb; Tumzabt: At Mzab) are a Berber ethnic group inhabiting the M'zab natural region in the northern Sahara of Algeria, numbering about 150,000 to 300,000 people. They primarily speak the Mozabite language, one of the Zenati languages in the Berber branch of the Afroasiatic family. Mozabites are primarily Ibadi Muslims, but there was a small population of Mzabi Jews as well.

Mozabites mainly live in five oases; namely, Ghardaïa, Beni Isguen, El Atteuf, Melika and Bounoura, as well as two other isolated oases farther north: Berriane and El Guerrara. Ghardaïa is the capital of the confederation, followed in importance by Beni Isguen, the chief commercial centre.
