This chapter begins with the arrival of Ibadi student Saʿīd al-Bārūnī in Cairo in 1798, just before the invasion of the French army under Napoleon. It follows the life of Saʿīd in Cairo during the tumultuous decades of the early nineteenth century, including the departure of the French and the rise to power of the Ottoman governor Muḥammad ʿAlī. Following his return to the Maghrib, the chapter continues the story of the Agency by turning to a private letter written to Saʿīd by one of his students, Muḥammad al-Bārūnī, who was studying at the Agency in the 1850s. The books and letters connected to the Agency in this period reveal much about the world of Cairene Ibadis in the mid-nineteenth century, including the state of education at al-Azhar, the changing demographics of the Ibadi community, and signs of a growing relationship between the Ibadi community of the Indian Ocean and that of northern Africa.
