Information: - Ab Manr Nizr al - Muafa li - Dnil - Lh ( 1045 - 1097 , Arabic : ) was the founder ( and an Imm ) of the Nizri branch of Ism '' il Shia Islam . Following the death of his father , Al - Mustansir Billah , he was deposed by his brother , Ahmad al - Musta '' l but his son , al - Hd ibn Nizr , escaped to Alamt and took refuge with believers there , thereby continuing the Immate . The followers of Nizr 's descendants constitute the majority of the Ism '' il today , with the smaller Musta '' l branch accepting his younger brother who overthrew him and the Druze ending the Immate before either of them . In his '' History of the Ismailis '' , A.S. Picklay says , '' Although Nizar was the rightful claimant to the throne after his father 's death , his younger brother Ahmad al - Musta '' l , supported by his father - in - law , the chief Vizier Badr al - Jamali , usurped all the power . '' He further writes , '' Mustaali , feeling insecure during Nizar 's existence , plotted against Imam Nizar and finally succeeded in making him a prisoner along with his two sons . '' In Egypt , Imam Nizar continued his struggle up to 490 A.H. , when he was killed . There have been some incorrect theories that Imam Nizar came to Alamut . Thus the Egyptian period of Ismaili Imams came to an end . - Ab Tamm Mad al-Mustanir bi-llh (; July 5, 1029 January 10, 1094) was the eighth caliph of the Fatimid Caliphate from 1036 until 1094.
