Q. I would like to know if i got my menstruation while keeping the fast of Aashura, do I now have to keep a Qadhaa fast of Aashura?
A. In principle, if a woman experiences Haidh during a fast, it is compulsory upon her to make Qadha of the fasts in which she experienced Haidh. The same ruling applies to a woman who experienced Haidh whilst observing the fasts of Ashura i.e. it is compulsory upon her to make Qadha of the Ashura fasts in which she experienced Haidh. (Badaai-us-Sanaai’ 2/94)
