Do vaginal discharges nullify ablution, and what should a woman do if she cannot perform ablution for every prayer?

If the discharge is continuous, its ruling is similar to that of istihadah (non-menstrual vaginal bleeding) and urinary incontinence. Wudu (ablution) is required for each prayer after its time has begun, and the emission of discharge after performing wudu does not invalidate it. If no discharge occurs until the next prayer time begins, it is permissible to pray with the same wudu. If performing wudu for each prayer becomes difficult, it is permissible to combine two prayers (Dhuhr and Asr, Maghrib and Isha) with a single wudu. The preponderant opinion is that discharges are pure, so washing clothes because of them is not obligatory, as there is no evidence to prove their impurity.
