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

the obligatory qadha.

certitude that it does not invalidate fast, Kaffarah will not be obligatory on
him.
