Khuzaima Qutbuddin

Abu Taher Khuzaima Qutbuddin (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, 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.

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". 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. On 23 April 2024, the Bombay high court dismissed the suit challenging Syedna Mufaddal Saifuddin's position as the 53rd Dai-al-Mutlaq of the Dawoodi Bohra Community. The court dismissed Taher Fakhruddin(son of Khuzaima Qutbuddin)'s claim and upheld Syedna Mufaddal as Dai-ul-Mutlaq..
