List of extinct Shia sects

The following is a list of extinct heterodox movements within Shia Islam. These are movements that no longer have any living followers or practitioners. These movements were created around certain beliefs that were unorthodox and not held by the mainstream Shia Muslims. These movements eventually, after their very brief existence, had their followers fall into mainstream Islam.

[Ghulat] sects

Bazighiyya- who believed that Ja'far al-Sadiq was God.
Dhammiyya- who believed that Ali was God and Muhammad was his appointed Messenger and Prophet.
Ghurabiyya- who believed the angel Gabriel was mistaken.
Ibrahimiyya– who believed in many heterodox practices influenced by their Qizilbash predecessors
Hurufiyya- who believed God is incarnated in every atom, reminiscent of the Alevi-Bektashism.
* Nuqtavi- who believed in a cyclical view of time, reminiscent of the Isma'ili Shia.
Kaysanites- who believed in the Imamate of Muhammad ibn al-Hanafiyyah after the death of Husayn Ibn 'Ali Ibn abu Talib.
* Bayaniyya- the followers of Bayān al-Nahdi, who believed that Abu Hashim was a prophet and would return to rule the world as Mahdi. Bayān claimed prophethood for himself after the demise of Abu Hashim, as well.
* Harbiyya or Harithiyya- the followers of ʿAbd Allāh ibn al-Harb ibn al-Kindi, who initially taught antinomianism then joined Ibn Mu'awiya's party and later expressed many extremist views about him. Furthermore, Ibn al-Harb introduced some fundamental doctrines including metempsychosis, cyclical history of eras and aeons into the radical branch of Shi'ism. The group claimed that Abu Hashim designated Ibn Mu'awiya as his successor Imam of Hashimiyya.
** Riyahiyya- Harbiyya and pro-Abbasid Hashimiyya disputed over Abu Hashim's will about the imamate and eventually the disputed parties agreed upon the arbitration of their respected leader Abu Riyah, who decided that the imamate should remain in Abbasids. Most of the followers of Harbiyya, who had previously recognized Ibn Mu'awiya as their imam, seceded and joined to the Abbasid party and they had been called Riyahiyya. Those who stayed in Harbiyya and continued to recognize the imamete of Ibn Mu'awiya subsequently called as Janahiyya.
** Janahiyya- the followers of ʿAbd Allāh ibn Mu'awiya ibn ʿAbd Allāh ibn Ja'far, who was a descendant of Ja'far ibn Abi Talib known as Dhu'l-Janahayn, believed incarnation of God in a succession of Prophets and imams passing eventually through Ibn al-hanafiya and Abu Hashim to Ibn Mu'awiya; transmigration of the souls; and the allegorical interpretation of the Quran.
Mughiriyya- who were influenced by Mandean and Manichean doctrines and were founded by the first Shi'i gnostic al-Mughira, who claimed that God is a man of light with a crown of light on his head resembling Mandean doctrine of deity referred to as "king of light". Al-Mughira further added that God has limbs corresponding to the letters of Arabic alphabet reminiscent of the teaching of Marcus the Gnostic.
Rawandiyya- who believed in the transmigration of souls. They asserted that the spirit that was in Jesus was in Ali, and the spirit of Adam was in Othman ibn Nahik.
Ya’furiyya- who believed in reincarnation and that Mu’ammar al-Kufi was their Lord.
Soldiers of Heaven- who believed that their former leader Dia Abdul Zahra Kadim was the Mahdi and reincarnation of Ali ibn Abi Talib.
