Note 42 — Chapter V
Edward William Lane translation
Note 42. Some mosques (as the Azhar, for instance, the principal mosque of Cairo) remain open all night; and many houseless persons sleep in them, upon the matting which covers the paved floor. Men are also often seen, at other times, but not at the hours of prayer, lounging, eating, or working, in the mosques; such practices not being deemed inconsistent with the high respect which the Muslims pay to these buildings.
