Should a woman stop praying and fasting if a brownish liquid mixed with a little blood is discharged from her?

If the yellowish or brownish discharge, along with any blood, persists for a day and a night, and it occurs during the usual time of menstruation, or fifteen days or more after the purification from the previous menses, then it is considered menstruation. Prayer and fasting are prohibited with it, because the brownish or yellowish discharge during the time of menstruation is considered menses, especially if it is mixed with blood.
