[2] 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 (Barelvi, Deobandi, Salafism, Wahhabism).
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).
[7] Shīʿas believe ʿAlī ibn Abī Ṭālib is the true successor to Muhammad, while Sunnīs consider Abu Bakr to hold that position.
All mainstream Twelver and Ismāʿīlī Shīʿa Muslims follow the same school of thought, the Jaʽfari jurisprudence, named after Jaʿfar al-Ṣādiq, the sixth Shīʿīte Imam.
The term Sunnī comes from the word sunnah, which means the teachings, actions, and examples of the Islamic prophet Muhammad and his companions (ṣaḥāba).
Sunnīs believe that Muhammad did not specifically appoint a successor to lead the Muslim community (Ummah) before his death in 632 CE, however they approve of the private election of the first companion, Abū Bakr.
[20][full citation needed] Shīʿīte groups and movements who either ascribe divine characteristics to some important figures in the history of Islam (usually members of Muhammad's family, the Ahl al-Bayt) or hold beliefs deemed deviant by mainstream Shīʿa Muslims were designated as Ghulat.

Absolute authority is given to the Quran and ḥadīth literature; new innovations accepted on the basis of qiyas (analogical reasoning) were rejected as bid'ah (heresy) by the Ibadis.
They rely on the Qur'an, the Sunnah, and sayings of the Sahaba, seeing this as the middle path where the attributes of Allah are accepted without questioning their nature (bi-la kayf).
[citation needed] Murji'ah was a name for an early politico-religious movement which came to refer to all those who identified faith (iman) with belief to the exclusion of acts.

[110] Sunni Muslims of the Indian subcontinent comprising present day India, Pakistan and Bangladesh who are overwhelmingly Hanafi by fiqh have split into two schools or movements, the Barelvi and the Deobandi.
The Al-Ikhwan Al-Muslimun (with Ikhwan الإخوان brethren) or Muslim Brotherhood, is an organisation that was founded by Egyptian scholar Hassan al-Banna, a graduate of Dar al-Ulum.
It was founded in Lahore, British India, by Sayyid Abul Ala Maududi (with alternative spellings of last name Maudoodi) in 1941 and is the oldest religious party in Pakistan.

[138] Mahdavia, or Mahdavism, is a Mahdiist sect founded in late 15th century India by Syed Muhammad Jaunpuri, who declared himself to be the Hidden Twelfth Imam of the Twelver Shia tradition.
[150] At the end of the 1950s, the movement reached a wider public, as the Egyptian president Gamal Abdel Nasser discovered the usefulness of pan-Islamism for his foreign policy.
[158] In recent years, Jihadi-Salafist doctrines have often been associated with the armed insurgencies of Islamic extremist movements and terrorist organizations targeting innocent civilians, both Muslims and Non-Muslims, such as al-Qaeda, ISIL/ISIS/IS/Daesh, Boko Haram, etc.
[159][160][157][158] The second largest group are the Salafi activists who have a long tradition of political activism, such as those that operate in organizations like the Muslim Brotherhood, the Arab world's major Islamist movement.
The most numerous are the quietists, who believe in disengagement from politics and accept allegiance to Muslim governments, no matter how tyrannical, to avoid fitna (chaos).
[157] The Wahhabi movement was founded and spearheaded by the Ḥanbalī scholar and theologian Muhammad ibn ʿAbd al-Wahhab,[161][162][163] a religious preacher from the Najd region in central Arabia,[164][165][166][167][168] and was instrumental in the rise of the House of Saud to power in the Arabian peninsula.
[165][166][167][168] His works were generally short, full of quotations from the Quran and Hadith literature, such as his main and foremost theological treatise, Kitāb at-Tawḥīd (Arabic: كتاب التوحيد; "The Book of Oneness").
[165][166][167][168] He taught that the primary doctrine of Islam was the uniqueness and oneness of God (tawḥīd), and denounced what he held to be popular religious beliefs and practices among Muslims that he considered to be akin to heretical innovation (bidʿah) and polytheism (shirk).
[165][166][167][168] Wahhabism has been described as a conservative, strict, and fundamentalist branch of Sunnī Islam,[169] with puritan views,[169] believing in a literal interpretation of the Quran.
[161] The terms "Wahhabism" and "Salafism" are sometimes evoked interchangeably, although the designation "Wahhabi" is specifically applied to the followers of Muhammad ibn ʿAbd al-Wahhab and his reformist doctrines.
