The Mouride brotherhood (الطريقة المريدية, Aṭ-Ṭarīqat al-Murīdiyya or simply مريدية, Murīdiyya in Arabic) is a large Islamic Sufi order (ṭarīqa) most prominent in Senegal and The Gambia, with headquarters in the holy city of Touba, Senegal (Tuubaa in Wolof, طوبى, Ṭūbā in Arabic). Mourides sometimes call their order the Way of Imitation of the Prophet. The followers are called mourides (murid in Wolof), from the Arabic word murīd (literally "one who desires"), a term used generally in Sufism to designate a disciple of a spiritual guide (murshid).
