Is it permissible for a menstruating woman or a person in a state of major ritual impurity to enter the mosque to listen to a lesson of knowledge? And what is the ruling on the hadith: (I do not permit the mosque to a person in a state of major ritual impurity or a menstruating woman)?

Al-Huwaini: Is it permissible for a menstruating woman to enter the mosque to listen to a lesson of knowledge or the like?

The Shaykh : Yes, for that and for other purposes.
Al-Huwaini: And for other purposes.

The Shaykh : Yes.
Al-Huwaini: This is the opinion of Ibn Hazm, but Imam al-Nawawi in al-Majmu' says something different.

The Shaykh : If someone else said it.
Al-Huwaini: I am just raising a difficulty, perhaps it will open another door for us.

The Shaykh : No problem, your intention is acceptable but your wording is rejected.
Al-Huwaini: Okay, and what about a person in a state of major ritual impurity?

The Shaykh : Likewise.
Al-Huwaini: Is it permissible for him?

The Shaykh : How could it not be permissible for him? But it is recommended and desirable that he performs the ablution and purifies himself; because he is able to do so, unlike the menstruating woman. Here is the difference between them.
Al-Huwaini: So the transmitted hadith is weak, O our Shaykh.

The Shaykh: And that is...
Al-Huwaini: .

The Shaykh : Yes, it is weak.
Al-Huwaini: Weak.

The Shaykh : Rather, it is denounced, as Imam Ahmad says.
Al-Huwaini: Okay... weak, rather denounced, meaning is the text denounced or...

The Shaykh : No, I am saying now, quoting from Imam Ahmad, and naturally, upon examination, it is found to be denounced in meaning as well, because it contradicts the original principle, which is permissibility.
Al-Huwaini: Yes.

The Shaykh : And one should not depart from this except with a binding text, and that only if it is established.
Al-Huwaini: Yes.
