Is the fast of a woman who gets her periods while fasting invalidated?

In the Name of Allah, the Most Gracious, the Most Merciful.

As-salāmu ‘alaykumwa-rahmatullāhiwa-barakātuh.

1. In principle, the fast of a woman who experiences Haydh (Menstruation) for any period of time while fasting is invalidated. Moreover, the Fuqaha have stated that it is Wajib (Necessary) for such a woman to abstain from eating and drinking during the fasting time.[1]

2. It is not compulsory for a woman to fulfill the Qadha fasts missed due to Haydh (Menstruation) before the next Ramadhaan. However, it is recommended for such a woman to fulfill her Qadha fasts as soon as possible.[2]

And Allah Ta’āla Knows Best
