Hebtiahs Bohra
The Hebtiahs Bohra were a branch of Mustaali Ismaili Shi'a Islam that broke off from the mainstream Dawoodi Bohra after the death of the 39th Da'i al-Mutlaq in 1754. They were mostly concentrated in Ujjain in India with a few families who were Hebtiah Bohra. History of the Imāmī-Hebtiahs Bohra
