Is intercourse during menstruation subject to a penalty (*kaffarah*)?

Primary text

Intercourse during the state of menstruation necessitates a penalty of one Dinar. This is established through religious texts concerning the menstruating woman. This ruling is contrasted with situations where an oath not to approach a menstruating woman is broken; the penalty is due upon intercourse during menstruation, but not due for intercourse outside of that state.
