Mahmet the Ishmaelite was originally a Sadducee warlord known as Emir Ambrus who rose to prominence in Tachkastan having subjugated the Banu Qabisa. He went on to conquer the Patriarchates of Jerusalem, Antioch and Alexandria where he became renowned for his brutal suppression of the followers of Rebbe Yehoshua Minzaret. However, it is said that despite his war-crimes, Sophronius of Jerusalem invited him to pray in the Church of the Sepulchre. Although he declined he is said to have asked John of the Sedre to explain the Christian doctrine to him before ordering a translation of the New Testament form him to study. After Sophronius died, the Emir installed Abraham I as the first Armenian Monophysite Patriarch over the Patriarchate of Jerusalem. He is also said to have regarded the Coptic Pope Benjamin as the Holiest Man he had ever met. Under the influence of the three Monophysite Patriarchs of the Oriental Orthodox Church, it seems having consulted an Edumean Monk called Abu Turab and his translator Salman of Fars, the Emir took on the name Mahmet in devotion to the crucifixion, accepted the Mishnah promoted by Rebbe Yehoshua Minzaret being identified by Monophysites the Messianic Emanation of the Divine, but also decided to try and influence his subjects to accept Sadducee ideas (such as the Sadducee calendar) as [[HAGARIM]] without abandoning Monophysite Messianism. His ideas were more popular among the Manicheans of Tachkastan than among the Sadducees so he appointed from Hagarim a Manichean supporter of his ideas Maichean called [[Emir Tashik]] as his successor.
The new Emir Tashik had all of Mahmet's writings gathered together into a new religious Tome, sending a copy to Pope Martin while ordering all original copies of the Miqra to be destroyed. This led to his assassination and a great civil war in the Empire which lasted for 36 years.
After that, Abdul Malik promoted the idea that Emir Ambrus was actually just continuing an idea which had originated with a Manichean who had taught the Emir's Sadducee Predecessor in the Hijaz.
