Poverty in medieval Islam is an enormous topic. It isworth considering from a historian's point of view,especially in the light of what has beenaccomplished by historians of Rome, Byzantium, andthe medieval and modern West who have dealt withpoverty and the poor. But as always, the sources forIslamic history, especially for the formative earlycenturies, present difficulties. Here I wish to makea preliminary attempt at dealing with part of thisproblem. I shall begin by considering an event whichrepresents a turning point in the history of theMuslim poor, or more accurately, in the way povertyand the poor have been represented in modernhistorical scholarship on medieval Islam. Then Ishall suggest a way in which this event may be setin context, and a possible strategy for handlingsome of the relevant sources. This strategy involvesthe identification of different, competing ways inwhich the poor were defined in the first centuriesof Islam.
