What is the ruling on one who is afflicted with minor ritual impurity during tawaf, or who emits pre-seminal fluid due to looking? And what is the ruling on a woman who begins menstruating during tawaf?

The Shaykh : He says: Do we understand from your words that ritual purity is not obligatory in tawaf, regarding both major and minor ritual impurity? And if ritual impurity occurs during tawaf, such as a man emitting semen due to looking, or a small amount of fluid coming from a woman at the beginning of menstruation that does not soil her clothes, does this invalidate the tawaf...?
We spoke about the fact that tawaf... because a person in a state of major ritual impurity is not permitted to enter the mosque, so his staying there is forbidden and specifically prohibited. But it is said: What do you say if he performed wudu...? This is a matter for consideration, and the apparent view is that it is a principle of the Shaykh al-Islam (may Allah have mercy on him) that it is valid... As for the menstruating woman, if menstruation comes to her during tawaf, she must leave, and it is not permissible for her to enter the mosque, because menstruation invalidates tawaf.
... We permit every person to take a recording from Brother Musa, and there is no obstacle in it, because his recording is clear, good, and nothing is missed in it, if Allah wills. As for the issue of the large number of pages, it is true that the number is large, and it appears that the pages will not be sufficient. This, if Allah wills, we will study and see how we will handle it, if Allah wills.
From the later generations, is there one who is a memorizer who, if Allah wills, will recite to us?

The Shaykh : From the later generations? All of you are in the front.
The student: ...

The Shaykh : Huh?
