Entering the Masjid for listening to lectures only during her periods ! what is the ruling?

The majority of fuqaha’ of the four madhhabs are of the view that it is not permissible for a menstruating women to stay in the mosque. They quoted as evidence for that the report narrated by al-Bukhaari (974) and Muslim (890) from Umm ‘Atiyyah who said: “He (the Prophet (peace and blessings of Allaah be upon him)) commanded us on the two Eids to bring out the virgins and those who usually stayed in seclusion, but he told the menstruating women to keep away from the prayer-place of the Muslims.” 

The scholars of the Standing Committee were asked :

They replied: It is not permissible for a woman to enter the mosque when she is menstruating or bleeding following childbirth… as for passing through, there is nothing wrong with that if it is necessary and there is no risk of her contaminating the mosque, because Allaah says (interpretation of the meaning):

“nor when you are in a state of Janaaba (i.e. in a state of sexual impurity and have not yet taken a bath), except when travelling on the road (without enough water, or just passing through a mosque), till you wash your whole body”

[al-Nisa’ 4:43]

A menstruating woman is similar to one who is in a state of janaabah. And the Prophet (peace and blessings of Allaah be upon him) told ‘Aa’ishah to fetch him something from the mosque when she was menstruating.e

Shaykh Ibn ‘Uthaymeen (may Allaah have mercy on him) was asked: Is it permissible for a menstruating woman to attend halaqahs in the mosque?

 He replied: It is not permissible for a menstruating woman to stay in the mosque. As for passing through the mosque, there is nothing wrong with that, subject to the condition that there is no risk of the mosque being contaminated with the blood that is coming out of her. If it is not permissible for her to stay in the mosque, it is not permissible for her to go there to listen to halaqahs and recitation of Qur’aan, unless there is a place outside the mosque where the sound can reach via loudspeakers, in which case there is nothing wrong with her sitting there to listen to the dhikr. There is nothing wrong with a woman listening to dhikr and recitation of Qur’aan, as it is proven that the Prophet (peace and blessings of Allaah be upon him) used to lay his head in ‘Aa’ishah’s lap and recite Qur'aan when she was menstruating.

 But it is not permissible for a menstruating woman to go to the mosque and stay there to listen to dhikr or Qur’aan recitation. Hence when the Prophet (peace and blessings of Allaah be upon him) heard, during the Farewell Pilgrimage, that Safiyyah was menstruating, he said: “Has she detained us?” because he thought that she had not done tawaaf al-ifaadah, but they said that she had already done it. This indicates that it is not permissible to stay in the mosque even for acts of worship. And it is proven that the Prophet (peace and blessings of Allaah be upon him) told women to go out to the Eid prayer-place to pray and remember Allaah (dhikr), but he told the menstruating women to keep away from the prayer-place itself.

Allah knows the best ...
