Abū Dharr ʿAlī (Arabic: أبو ذر علي), also known by the regnal name of Nūr al-Dīn Muḥammad (Arabic: نور الدين محمد), was the 35th imam of the Qasim-Shahi branch of the Nizari Isma'ili community.
He succeeded his father, al-Mustansir Billah III, upon his death in 1498, at Anjudan.[1] He apparently married a sister or daughter of the Safavid shah of Persia, Tahmasp I.[1] Despite this close connection to the rulers of Persia however, the Safavids began to persecute all other varieties of Shi'ism that rivalled their own Twelver creed, and Tahmasp launched a persecution of the Nizaris during the reign of Abu Dharr Ali's son and successor, Murad Mirza.[2]
