The Risāla al-mūjāza al-kāfiya fī adab al-duʿāt (A Brief and Concise Treatise on the Code of Conduct for the Dāʿīs) constitutes the only extant work in Ismaili literature that deals with specific practical aspects of the Ismaili daʿwa, an appeal and encouragement to the faith.

Written by the Fatimid author Ahmad b. Ibrahim al-Naysābūrī (11th century CE), it represents a normative guide for the Ismaili dāʿīs, who functioned as the religious agents and ‘summoners’ responsible for the leadership, instruction and spiritual and social welfare of the Ismaili community.

Al-Naysābūrī’s enumeration of the dāʿīs’ ideal traits and attributes in the Risāla al-mūjāza belongs to the wider genre of ‘professional adab’ literature that exclusively addresses groups belonging to certain occupations and instructs them in specific ethical principles and codes of conduct, and which is prevalent in classical Muslim culture. It may also be located in the even older tradition of the Mirror of Princes literature, which dates back to pre-Islamic Persia, and which promoted the ideal practice of rulership.

Indeed, many of the characteristics of the dāʿī listed in the Risāla are consistent with the topoi in the Mirror of Princes literature as it relates to the ruler, namely the virtues of piety, chastity, uprightness, mercy, forgiveness, humility and generosity. In this regard, the communal functions of a da‘i also mirror the duties traditionally ascribed to a responsible ruler — that he has to maintain the community, protect the weak, and fight and punish crime, corruption and social disintegration — but with the one key distinction that they are, in this instance, always elaborated within the context of the Ismaili dawa.

The present work constitutes a critical edition and translation of the Risāla al-mūjāza al-kāfiya fī adab al-duʿāt. Al-Naysābūrī’s treatise is a fascinating testimony to the wide network of a class of individuals charged with proclaiming the daʿwat al-ḥaqq (‘call to truth’) over various frames of time and space. It is thus a valuable resource for students and scholars interested in medieval Islamic literature more generally and the structure and workings of the Fatimid daʿwa in particular.
