Narjis
Narjis (Arabic: نَرْجِس) is believed by the Twelvers to have been the mother of their Hidden Imam, Muhammad al-Mahdi. His birth is said to have been providentially concealed by his father, Hasan al-Askari, out of fear of Abbasid persecution as they sought to eliminate an expected child of the eleventh Imam, whom persistent rumors described as a savior.
