This paper refers to the actual condition of religious donation system, called Waqf among 46 existent wakala-s in Cairo, based on some findings of a field survey in 1994/95. Under the State Control of Waqf, the wakala-s in Cairo have lost the proper values and functions in present economic activities. Reviewing the outline of enterprises for waqf since the Mamluk period, their purpose and character have been changing gradually. In the framework of the system of waqf, however, these projects which were with constructing wakala-s as the central figure, have remained to play an important role in rehabilitating the stagnant districts by equipping with urban facilities.
