Are the continuous yellow discharges after menstruation considered menstruation, and is it obligatory to perform ghusl after the discontinuation of the brownish discharge while the yellowish discharge persists, or is it necessary to wait for the discontinuation of the yellowish discharge as well, and what should a woman do if the brownish discharge returns after performing ghusl from the yellowish discharge?

Continuous discharges are pure (tahira) but invalidate ablution (wudu'). The woman experiencing them is treated like one with chronic incontinence (salis), so she performs ablution for each prayer. Purity (tuhr) is identified by the white discharge (al-qassah al-bayda') or complete dryness. Yellowish and brownish discharges (as-sufrah wal-kudrah), if connected to menstruation, are considered menstruation. If they appear after purity has been established, they are not to be given any consideration.
