Answer:

Praise be to Allaah.

Al-Nawawi said: The ummah is unanimously agreed that it is haraam for a menstruating woman to pray, whether that is obligatory (fard) prayers or supererogatory (naafil).” Al-Majmoo’, 2/351. 

Shaykh Ibn ‘Uthaymeen was asked about that and replied: 

It is not permissible for a woman who is menstruating or bleeding following childbirth (nifaas) to pray, because the Prophet (peace and blessings of Allaah be upon him) said concerning women: “Is it not the case that if a woman menstruates she does not pray or fast?” The Muslims are unanimously agreed that it is not permissible for a menstruating women to fast, or for her to pray. Based on this, if a woman does that she has to repent to Allaah and to seek His forgiveness for what she did. 

Fataawa al-Mar’ah al-Muslimah, 1/285.

Whatever written of Truth and benefit is only due to Allah's Assistance and Guidance, and whatever of error is of me. Allah Alone Knows Best and He is the Only Source of Strength.
Your brother and well wisher in Islam
