The Sirat al-Ustadh Jawdhar was written during the time of al-Muizz's successor al-Aziz bi-llah (r. 365-386/975-996). It is divided into two parts. The first part contains an account of the life and career of Jawdhar, from his entering the service of the Fatimids under al-Mahdi to his death sixty years later during the reign of al-Muizz. The biography is interspersed with some sermons and correspondence of the imams with Jawdhar on a variety of subjects, both personal and political. The second part is largely a documentary collection of 86 letters, directives, recorded conversations and letters of the Fatimid caliph-imams addressed to Jawdhar. Altogether, this publication provides a unique insight into the private world and political ethos of one of the major Muslim dynasties of the medieval era.'.
