Abū Shuʿayb Muḥammad ibn Nuṣayr al-Numayri (Arabic: أبو شعيب محمد بن نصير النميري),[1] died after 868,[2] was considered by his followers as the representative (Bāb) of the tenth Twelver Imam, Ali al‐Hadi and of the eleventh Twelver Imam, Hasan al‐Askari, and founder of the Alawites.
Ibn Nusayr was known to his followers as a representative (Bab) of al‐Askari and of the twelfth Twelver Imam, Hujjat-Allah al-Mahdi during the Minor Occultation.
[3][4] A rival of his in claiming to be the bāb (door) to the Imams was Abu Yaqub Ishaq, founder of the Ishaqiyya.
His claim was rejected by the mainstream Shias, and Nusayr was later excommunicated by Abu Jafar Muhammad ibn Uthman, the official second deputy of the hidden Imam.
[11] Nusayr was also prone to these antics earlier in his career when he claimed al‐Hadi was in fact divine and that he had been sent by al‐Hadi as a prophet, because of this he was officially 'cursed' by the Shia community.
