After the death of Abdullah, Zoeb bin Moosa appointed Yaqub as the wali ("representative" or "caretaker") of the Tayyibi organization ("dawah") in India.

The Atba-e-Malak community are a branch of Mustaali Ismaili Shi'a Islam that broke off from the mainstream Dawoodi Bohra after the death of the 46th Da'i al-Mutlaq, under the leadership of Abdul Hussain Jivaji in 1840.
Taher Fakhruddin is also a claimant to the title of Dai al Mutlaq since 2016, although it is widely accepted that Syedna Mufaddal Saifuddin is the leader of the Dawoodi Bohras, in all aspects and administration.
