Muhammad bin Ali, surnamed al-Muhtadi is reported to have been born in 502/1109 at the castle of
Lambsar. He was the first Ismaili Nizari Imam to be born in Persia. He is also known as Muhtadi and Muhammad I. He became the Imam of the Nizari Ismailis after the death of his father, Imam al-Hadi, in the year 530 AH. His first move was to shift his headquarter to the fortress of
Alamut and he focused on developing the Ismaili Army (
Fidais) to be able to defend the Ismaili fortresses from the invaders. He also paid attention to the organisation of the
Da'is and to introducing them to the core principles of the Shia Ismaili Islamic beliefs. He also trained them to develop skills in articulating and debating issues dealing with philosophy, Islamic jurisprudence and Islamic beliefs. He also created an innovative coding system where numbers were used instead of letters, for safe internal and external communications to protect them from their enemies. Imam al-Muhtadi used to live a life of asceticism and austerity. In 1966, the
American Numismatic Society, New York acquired a coin from this time, minted in 553/1158. It was illustrated in the American Numismatic Society's Annual Report for 1966 (pl.III,2). George C. Miles gave its detail of the Alamut Coins (Orientalia Lovaniensa Periodica, 3–5, 1972–74, pp. 155–162). Its size is 14 mm., weighing 0.635 gm. Its obverse side bears the name, "Muhammad bin (Kiya) Buzrug Ummid" and in the marginal legend, the name of the mint, kursi al-Daylam and the date 553 A.H. (1158 A.D.) has been clearly inscribed. The reverse area begins with the Shi’ite formula: "Ali is the friend of God" and the next three lines read: al-Mustafa li-Dinillah, Nizar (Nizar, the chosen for the religion of God). These three lines are followed by the marginal legend: amir al-mo’minin, salwat Allah alayhi wa-ala aba’ihi al-tahirin wa-abna’hi al-akramin (the blessings of God be upon him and upon his ancestors, the pure ones; and upon his descendants, the most honourable ones). George C. Miles reproduced the photographs of the six coins: There are few other coins minted at kursi al-Daylam with the same legends, differing only in dates. It implies that the six coins from above had been struck during the period of Imam al-Muhtadi (530-552/1136-1157), and the two coins during the period of Imam al-Qahir (552-557/1157-1162). Imam al-Muhtadi was also taking care of the horses bred by his father in the fortress of Lamasar. He is also reported to have taken several visits of surrounding castles in Rudhbar. He died in 552/1157 at the age of 52 years. He vested the office of Imamate to his elder son,
Hasan al-Qahir. ==References==
