Question
During the month of Ramadan and after breaking her fast at sunset, a woman intended to perform ablution for Maghrib prayer but detected the commencement of menses in the form of a brown secretion which preceded blood flow. It seemed to her to have begun flowing a short while earlier. Should she make up for the fasting of that day, as she was not fully certain of whether or not it flowed from her before or after sunset? Perhaps it flowed before the Maghrib Athaan (call to prayer) while she was unaware.
Fatwa
All perfect praise be to Allah, the Lord of the Worlds. I testify that there is none worthy of worship except Allah, and that Muhammad, salallaahu alayhi wa sallam, is His Slave and Messenger.
The brown fluid she experienced known as the ‘brownish discharge’ is considered menses only if it flowed from her at the time of her usual menstruation. In case it is considered as menses and she was unsure as to whether it flowed from her before or after sunset, then her fast is valid because menstruation is considered to exist only at the time when she first became aware of it, for the general rule is attributing an incident (menses in our case) to the most recent time (after sunset in our case) and not earlier than that.
Allah Knows best.
