Niche or opening in a wall (kawwa)

Kawwa, in lexicon, is a hole in a wall, plural kawat or kuwa, also called rawshan; in law it is an opening made in the wall of a house for light, or a recess cut into it without passing through, for setting goods; some jurists explain it as a niche ¹.

Jurists differ on whether a man may act on his own property in a way that harms his neighbour, such as opening a window that looks into the neighbour's house. Some allow it, some forbid it, and others distinguish; the detail is in the entries on neighbourly rights, the wall, use of property and overlooking ¹.
