Problem: Information: - A caliphate ("khilfa") is an area containing an Islamic steward known as a caliph ("" )a person considered a religious successor to the Islamic prophet, Muhammad (Muhammad ibn Abdullh), and a leader of the entire Muslim community. The Rashidun caliphs, who directly succeeded Muhammad as leaders of the Muslim community, were chosen through "shura, "a process of community consultation that some consider to be an early form of Islamic democracy. During the history of Islam after the Rashidun period, many Muslim states, almost all of them hereditary monarchies, have claimed to be caliphates. - 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.

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 . - A Muslim is someone who follows or practises Islam, a monotheistic Abrahamic religion. Muslims consider the Quran (Koran), their holy book, to be the verbatim word of God as revealed to the Islamic prophet and messenger Muhammad. They also follow the teachings and practices of Muhammad ("sunnah ") as recorded in traditional accounts ("hadith"). "Muslim" is an Arabic word meaning "one who submits (to God)". - The Fatimid Caliphate ("") was an Ismaili Shia Islamic caliphate that spanned a large area of North Africa, from the Red Sea in the east to the Atlantic Ocean in the west.
