Ghulat

The '''''' () were a branch of early Shi'a Islam. The term mainly refers to a wide variety of extinct Shi'i sects active in 8th- and 9th-century Kufa in Lower Mesopotamia, and who, despite their sometimes significant differences, shared several common ideas. These common ideas included the attribution of a divine nature to the Imams, metempsychosis (the belief that souls can migrate between different human and non-human bodies), a particular gnostic creation myth involving pre-existent 'shadows' (azilla) whose fall from grace produced the material world, and an emphasis on secrecy and dissociation from outsiders. They were named ghulat by other Shi'i and Sunni Muslims for their purportedly "exaggerated" veneration of Muhammad (–632) and his family, most notably Ali (–661) and his descendants, the Imams.

The ideas of the ghulat have at times been compared to those of the late antique gnostics, but the extent of this similarity has also been questioned. Some ghulat ideas, such as the notion of the occultation () and return (''raj'a'') of the Imam, have been influential in the development of Twelver Shi'ism. Later Isma'ili Shi'i authors such as Ja'far ibn Mansur al-Yaman (died ) and Abu Ya'qub al-Sijistani (died after 971) also adapted ghulat ideas to reformulate their own doctrines. The only ghulat sect still in existence today are the Alawites, historically known as Nusayris after their founder Ibn Nusayr (died after 868).
