Do natural vaginal discharges, which are constant, invalidate ablution?

Vaginal discharge is pure (tahir), but it nullifies ablution (wudu') according to the majority of scholars. A woman afflicted with the continuous flow (sals) of these discharges should perform ablution for each prayer after its time has begun. If the discharges are constant, there is no need to make up (qada') the prayers, acting upon the view of the Malikis, who do not obligate ablution for someone experiencing sals, especially after the act has occurred and it is difficult to rectify, or acting upon the view of those who do not deem qada' necessary for someone ignorant of a condition or pillar. As a precautionary measure (ihtiyat), one may make up the prayers that are most likely deemed obligatory.
