All perfect praise be to Allaah, The Lord of the Worlds. I testify that there is none worthy of worship except Allaah, and that Muhammad is His slave and Messenger. We ask Allaah to exalt his mention as well as that of his family and all his companions.
A woman in menses is not obliged to wash her private parts, as this kind of washing does not lead to performing any act of worship; as long as a woman continues to have blood then she is still in menses [and she cannot perform any act of worship]. Ibn Rushd said: 'There is no difference between becoming pure from menses and post partum bleeding; a woman does not become pure if these are connected; a woman becomes pure only when both stop.'
Allaah Knows best.
