Explore this subject in depth
Learn how to compare a legal school, a theological approach and a spiritual order without mixing categories. The guide covers source attribution, internal diversity and respectful discussion of disagreement.
An introduction to Muslim legal schools, theological traditions, communities and Sufi orders. Learn how the categories overlap, then follow the sources behind each overview.
Read across traditions with care
Fiqh concerns jurisprudence; kalam concerns systematic theology; a tariqah is a spiritual path or lineage. A person may identify with more than one of these categories at the same time. An overview should describe a community’s beliefs without using its opponents’ judgments as neutral facts.
A shared point of reference
The Amman Message recognizes followers of the four Sunni legal schools, Ja‘fari and Zaydi schools, Ibadi law and the Zahiri school as Muslims, and rejects declarations of apostasy between them. Its text also discusses qualified authority for religious rulings. This is a named inter-Muslim declaration, not a claim that every scholarly disagreement has disappeared.

Explore the texts behind the traditions
Explore fifteen original English guides to Sunni, Twelver, Ibadi and Zaydi hadith works, Ismaili legal literature and a related Sufi manual. All fifteen guides are also available in Urdu and Arabic. Each guide identifies its genre and scholarly context; these works are not presented as one canon shared identically by every Muslim school.
Sunni legal schools and movements
Legal schools and later movements are related, but they are not interchangeable categories. Begin with the four classical schools, then study the South Asian and reform movements in their historical settings.
Barelvi / Ahl-e-Sunnat
South Asian Sunni scholarly and devotional movement
Salafi / Ahl-e-Hadith
Related reform orientations with distinct histories
Shi‘i traditions
Twelver, Ismaili and Zaydi traditions have distinct accounts of authority and succession. The Bohra and Nizari introductions explain branches within Ismaili history rather than listing them as unrelated religions.
Ibadi tradition
Ibadi Islam is presented separately from Sunni and Shi‘i traditions, with its own history, texts and scholarship.
Sufi orders
A tariqah or silsilah concerns spiritual training and transmission. A Sufi affiliation can overlap with a legal and theological affiliation; it is not a complete substitute for either.
Theology and historical movements
Ash‘ari and Maturidi theology remain living traditions. Mu‘tazili thought and groups described as Khawarij require historical study. This grouping does not imply that all four have the same present-day status.

Scope of these introductions
These pages provide history, terminology and reading sources. Detailed, school-by-school manuals for prayer, fasting, pilgrimage, zakat and khums are a separate research task and are not implied by the presence of an overview. Personal rulings should be sought from a qualified scholar in the relevant tradition.
