Chapter 6 turns its attention to the fourth work of Ibadi prosopography, the fourteenth-century Kitab al-jawahir by Abu al-Qasim al-Barradi. This book departs radically from its predecessors by extending the written network backward in time all the way to the very beginnings of Islam. Al-Barradi claims for Ibadism some of the earliest Companions of the Prophet Muhammad in the seventh century and retells the history of Islam all the way up to the Rustamid dynasty. I show that this "retroactive" networking allows al-Barradi to present Ibadi history as the history of Islam itself. In addition to comprising a history of Islam, the Kitab al-jawahir also includes a list of books known to its author in the fourteenth century. I conclude the chapter by showing what this book list—comprising eastern and western Ibadi works from several centuries—reveals (and conceals) about Ibadi manuscript collections in the fourteenth century. In addition, I demonstrate that the book list complements al-Barradi’s history in linking Ibadi books from both east and west, bringing them together to produce a canonical list of the community’s literature.
