Khuzaima_Qutbuddin
Abu Taher Khuzaima Qutbuddin[1][2] (5 June 1940 – 30 March 2016) was the son of the 51st Da'i al-Mutlaq, half brother of the 52nd Da'i and a Mazoon of the Dawoodi Bohras,[3][4] a subgroup within the Mustaali, Ismaili Shia branch of Islam. Qutbuddin was appointed as Mazoon by the Da'i al-Mutlaq, Syedna Muhammad Burhanuddin in 1965.[5]
Qutbuddin, a half-brother of Syedna Mohammed Burhanuddin and a rival claimant to the title of Dai-al-Mutlaq, claimed that his half-brother appointed him heir in 1965 while conferring on him the title of "mazoon".[6][7] Contrary to the claim, Mufaddal Saifuddin son of Late Syedna Burhanuddin claimed that his father had declared "nass" (succession) on him in London on 4 June 2011, and many times before.[8][9][10][11]
