Traditionalist theology (Islam) in the context of "Islamic theology"

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).

Ash'arism (/æʃəˈriː/; Arabic: ٱلْأَشْعَرِيّةُ, romanized: al-Ashʿarīyya) is a school of theology in Sunni Islam named after Abu al-Hasan al-Ash'ari, a Sunni jurist, reformer (mujaddid), and scholastic theologian, in the 9th–10th century. It established an orthodox guideline, based on scriptural authority, rationality, and theological rationalism. It is one of the three main schools alongside Maturidism and Atharism.

Al-Ash'ari established a middle way between the doctrines of the Atharī and Muʿtazila schools of Islamic theology, based both on reliance on the sacred scriptures of Islam and theological rationalism concerning the agency and attributes of God. Ashʿarism eventually became the predominant school of theological thought within Sunnī Islam, and is regarded as the single most important school of Islamic theology in the history of Islam.

Maturidism (Arabic: المَاتُريدِيَّةُ, romanized: al-Māturīdiyya) is a school of theology in Sunni Islam named after Abu Mansur al-Maturidi. It is one of the three creeds of Sunni Islam alongside Ash'arism and Atharism, and prevails in the Hanafi school of jurisprudence.

Al-Maturidi codified and systematized the theological Islamic beliefs already present among the Ḥanafite Muslim theologians of Balkh and Transoxiana under one school of systematic theology (kalām); Abu Hanifa emphasized the use of rationality and theological rationalism regarding the interpretation of the sacred scriptures of Islam.

Ahl al-Hadith (Arabic: أَهْل الحَدِيث, romanized: Ahl al-Ḥadīth, lit. 'people of hadith') is an Islamic school of Sunni Islam that emerged during the 2nd and 3rd Islamic centuries of the Islamic era (late 8th and 9th century CE) as a movement of hadith scholars who considered the Quran and authentic hadith to be the only authority in matters of law and creed. They were known as "Athari" for championing traditionalist theological doctrines which rejected rationalist approaches and advocated a strictly literalist reading of Scriptures. Its adherents have also been referred to as traditionalists and sometimes traditionists (from "traditions", namely, hadiths). The traditionalists constituted the most authoritative and dominant bloc of Sunni orthodoxy prior to the emergence of mad'habs (legal schools) during the fourth Islamic century.

In jurisprudence, Ahl al-Hadith opposed many of their contemporary jurists who based their legal reasoning on informed opinion رَأْي (raʼy) or living local practice عُرْف (ʽurf), who were referred to, often derogatorily, as Ahl ar-Ra'y. The traditionalists condemned the practice of taqlid (following scholarly opinions or ra'y without asking for scriptural proofs) and advocated ittiba (adherence to scholarly traditions by asking for proofs from the Quran and Sunnah and taking only their literal meaning). In turn, the Ahl al-Hadith upheld ijtihad (scholarly legal reasoning) by adhering to Scriptures.
