What is the ruling regarding the continuity of sequential fasting if the fasting woman enters menstruation (Hayd) before completing the two months?

Al-Mughni
Book of Zihar
Primary text
Scholars have reached a consensus that a fasting woman who enters menstruation before completion must resume and build upon her previous fasting days once she becomes pure. This is because avoiding menstruation during those two months would necessitate delaying the fast until menopause, which endangers the fulfillment of the atonement due to potential death before that time. The rationale is that menstruation is an unavoidable circumstance.

Postpartum bleeding (Nifas) has two views: one view holds that Nifas does not interrupt the sequence because it is treated like menstruation in its rulings, and the bleeding is not due to the woman's voluntary action, making the time akin to the night for the fasting person. The second view holds that Nifas does interrupt the sequence because it is a temporary cessation of purity that could potentially be avoided by delaying the fast, thus treating it like breaking the fast without an excuse.
