Q: Can women make Wudhu in menstruation? I have heard that menstruating women, after listening to each athaan, should make Wudhu and sit on the prayer mat and do zikr? Is it true?
A: It is permissible for a woman to make Wudhu and sit on her musalla (prayer mat) to make zikr during haiz (menstruation). She does not need to wait for athaan, she can do this any time during the namaaz time.
But she cannot read quran in this state and she cannot touch the quran.
Also note that this is permissible, it is not necessary or wajib
