Ruling on the substance that comes out of a woman before the onset of menstruation

Question: This questioner says in a second question: Before the monthly period arrives, a brownish substance comes out of me that lasts for five days, and after that the normal blood comes and lasts for eight days after the first five days. She says: I pray during these five days, but I ask: Is it obligatory for me to fast and pray during these days or not? Please inform us, may Allah reward you.

Answer: If the five brownish days are separate from the blood, they are not part of menstruation. You must pray and fast during them and perform wudu for every prayer; because it is in the ruling of urine, and it does not have the ruling of menstruation. Therefore, it does not prevent prayer or fasting, but it necessitates wudu every time until it stops, like the blood of irregular bleeding.
As for if these five days are connected to the menstruation, they are part of the menstruation and are counted from the custom. You must not pray or fast during them.
Likewise, if this dark or yellow substance comes after the purity from menstruation, it is not considered menstruation. Rather, its ruling is the ruling of irregular bleeding. You must clean yourself from it every time, perform wudu, and pray and fast. It is not counted as menstruation, and you are lawful for your husband. This is based on the statement of Umm Atiyyah (may Allah be pleased with her): "We did not consider the dark or yellow substance after purity to be anything." Al-Bukhari narrated it in his Sahih, and Abu Dawud, and this is his wording. Umm Atiyyah is one of the noble female Companions who narrated many hadiths from the Prophet (peace and blessings be upon him) (may Allah be pleased with her). And success is from Allah.
