Fateh Daud was the Ismaili Shi'a ruler of Multan[1] deposed by Mahmud Ghazni[2] who also massacared the Ismailis [3] of Multan in the course of his conquest
The Ismaili ruler of Multan fled to a fort where he immured himself and was finally pardoned by Mahmud on promise of payment of ransom.[4] Abul Fatah Daud offered a yearly tribute of 200000 golden dirhams and abjuration of Isma'ili faith. The terms were accepted, and Mahmud also exacted 2 million dirhams from the population of Multan by force.[5]
Despite the hostilities of the Ghaznavids and their successors , Ismailism survived in Sindh and later received the protection of the Sumras, who ruled independently from Thatta, for almost three centuries starting 1051 AD.[6]
