Manuscripts of Ahmad al-Naysaburi

An important Shi‘i Ismaili scholar and writer of the early 5th/11th century, Ahmad b. Ibrahim al-Naysaburi flourished during the reigns of Fatimid imaminfo-icon-caliphs al-‘Aziz (AH 365/975-386/996 CE) and al-Hakim bi-Amr Allah (AH 386/996-411/1021 CE). Very little information about his personal life is available, but a great deal of talent, character and cultural background can be gleaned from his works. His nisbainfo-icon Nishapuri (Naysaburi in Arabic) suggests he came from Nishapur, the centre of the Ismaili da‘wainfo-icon in Khurasaninfo-icon, particularly noted for its dialectic outlook. It was in a social and intellectual milieu such as this that al-Naysaburi was to develop his own thought with a particularly heightened interest in philosophical learning. His works reveal that he was a versatile scholar writing on history, theology, eschatology as well as literature. The fact that several of his works have survived portrays the appeal and significance of his thought, allowing us also to understand the beliefs of his own time.

Istitar al-imam





Istitar al-imam Among al-Naysaburi's many works is the Istitar al-imam, an important historical work which reveals names of the three succeeding Ismaili imams after Muhammad b. Ismail b. Ja‘far al-Sadiq. The Russian scholar, Wladimir Ivanow (d. 1970), observes that in it “we have precious crumbs of information about a period which is a lost world in history, information which cannot be found anywhere else." 1

Risala al-mujiza al-kafiya





Risala al-mujiza al-kafiyaNaysaburi’s Risala al-mujiza belongs to a genre of literature called adabinfo-icon (meaning appropriate behaviour) and gives a detailed description of the characteristics and duties of a da‘iinfo-icon. Ivanow’s article on the organisation of the da‘wa in Fatimid times was based on this treatise.2

Ithbat al-imamainfo-icon





Ithbat al-imamaAl-Naysaburi’s theological works include the Ithbat al-imama where the author uses philosophy as a tool to explain his theology. He affirms the Imamatinfo-icon on the basis of rational and philosophical arguments in addition to his use of the Qur’aninfo-icon and hadithinfo-icon. The work is an Ismaili representative of a genre of works on the subject of the Imamat.


An Arabic edition and an English translation of the Ithbat al-Imama by Dr Arzina R Lalani, a Research Associate at The Institute of Ismaili Studies, is now published by the Institute.
