Atba-i-Malak
The Abta-i Malak jamaat (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. They have further split into two more branches, the Atba-e-Malak Badar and Atba-i-Malak Vakil.
