Praise be to Allaah.
With regard to the secretions that occur in women when
pregnant and otherwise, if they come from the uterus – which is usually
the case – they are taahir (pure), but if they come from the urethra, then
they are impure (najis).
These secretions do not necessitate ghusl, but they do
invalidate wudoo’, unless they are ongoing and do not cease, in which case
they come under the same rulings as incontinence, so wudoo’ must be done for
each prayer after the time for prayer begins.
Shaykh Ibn ‘Uthaymeen (may Allah have mercy on him) said:
What appears to me to be the case after studying the matter is that the
fluid that is emitted by a woman, if it does not come from the urethra and
in fact comes from the uterus, is pure (taahir).
This is the ruling on these secretions with regard to purity
(tahaarah): they are pure (taahir) and do not make the clothing or body
With regard to the ruling when it comes to wudoo’, this
secretion invalidates wudoo’ unless it is continual, in which case it does
not invalidate wudoo’, but the woman should not do wudoo for prayer until
after the time of the prayer has begun and she has taken protective
But if it stops and starts, and it usually stops during the
times of prayer, then she should delay the prayer until the time when it
stops, so long as she does not fear that the time for the prayer will end.
If she is afraid that the time for prayer will end, then she should do
wudoo’ and take protective measures and pray. It makes no difference whether
the discharge is small or great, because it is all coming from the same
place, so either a little or a lot of it invalidates wudoo’.
End quote from Majmoo‘ Fataawa Ibn ‘Uthaymeen
What is meant by “taking protective measures” is that she
should put a piece of cloth or cotton or the like over her private part so
that it will absorb whatever comes out of this fluid and prevent it
spreading on her garments or body.
