(“House of Learning”), the leading Muslim theological centre (madrasah) of India. It was founded in 1867 by Muḥammad ʿĀbid Ḥusayn in the Sahāranpur district of Uttar Pradesh. The theological position of Deoband has always been heavily influenced by the 18th-century Muslim reformer Shāh Walī Allāh and the early 19th-century Indian Wahhābīyah, giving it a very puritanical and orthodox outlook.

The program of studies is highly traditional, stressing jurisprudence (fiqh), Qurʾānic exegesis (tafsīr), the study of traditions (Ḥadīth), scholastic theology (kalam), and philosophy (falsafah). Modern disciplines, which are not relevant to a proper knowledge of Islām and can lead to sinful innovation (bidʿah), are ignored, and the modern practice of Islām is studied only in order to purify it of unorthodox accretions. The student is thus prepared mainly for religious leadership of the Muslim community.

Deoband's enrollment of about 1,500 students is culled from all parts of the Muslim world. The madrasah boasts a library of 67,000 printed books and manuscripts in Arabic, Persian, and Urdu. A mosque, lecture halls, and student residences further serve the scholarly community.
