mullah, a Muslim title generally denoting “lord”; it is used in various parts of the Islāmic world as an honorific attached to the name of a king, sultan, or other noble (as in Morocco and other parts of North Africa) or of a scholar or religious leader (as in parts of the Middle East and the Indian subcontinent). The term appears in the Qurʾān in reference to Allāh, the “Lord” or “Master,” and thus came to be applied to earthly lords to whom religious sanctity was attributed.
The most common application of the title mullah is to religious leaders, teachers in religious schools, those versed in the canon law, leaders of prayer in the mosques (imams), or reciters of the Qurʾān (qurrāʾ). There are no formal requirements for acquisition of the title, but normally persons called by it have had some training in a madrasah, or religious school. The word is often used to designate the entire class that upholds the traditional interpretation of Islām.
