Divine leadership has continued in the Bohra branch through the institution of the "Unrestricted Missionary" Dai. According to Bohra tradition, before the last Imam, At-Tayyib Abi l-Qasim, went into seclusion, his father, the 20th Al-Amir bi-Ahkami l-Lah, had instructed Al-Hurra Al-Malika the Malika (Queen consort) in Yemen to appoint a vicegerent after the seclusion—the "Unrestricted Missionary", who as the Imam's vicegerent has full authority to govern the community in all matters both spiritual and temporal while the lineage of Mustaali-Tayyibi Imams remains in seclusion (Dawr-e-Satr). The three branches of the Mustaali, the Alavi Bohra, Sulaimani Bohra and Dawoodi Bohra, differ on who the current Unrestricted Missionary is.
