Obligatory Qadha Fast and Kaffarah

1667. In the following situations, both qadha and Kaffarah become obligatory, provided these acts are committed intentionally, voluntarily and without any force or pressure, during the fasts of Ramadhan:

Eating

Drinking

Sexual Intercourse

Masturbation

Staying in the state of Janabat till the time of Fajr prayers

And as a recommended precaution, invalidating the fast due to reasons other than those mentioned above, should also be recompensed with Kaffarah, besides the obligatory qadha.

1668. If a person commits any of the foregoing acts with an absolute certitude that it does not invalidate fast, Kaffarah will not be obligatory on him.
