What does one do if his ablution is broken during tawaf, and what is the ruling on tawaf without ablution?

The questioner : It is not permissible to begin tawaf except with ablution, but if the ablution is broken during the tawaf, does he have to complete his tawaf, and is there nothing required of him?

The Shaykh : It is like a woman who is menstruating; if she starts menstruating while she is performing tawaf, what does she do? She stops the tawaf, and so does he, but he is able to renew his ablution, and she renews her purity, if Allah wills, after a few days.

The questioner : He completes it, O Shaykh...

The Shaykh : That is, if he has completed two circuits, he needs five, and if he is left with half of the last circuit, he completes the half, and so on.

The questioner : The Shaykh : Ibn Uthaymeen says that it is permissible for him to perform tawaf if his ablution is broken during the tawaf. I do not know if you have anything in mind regarding this?

The Shaykh : No, but this may be because he does not consider purity to be a condition for tawaf.

The questioner : He said no, it is not permissible for him to perform tawaf without ablution, but if he begins the tawaf and then his ablution is broken during the tawaf, he must complete his tawaf and there is nothing required of him.

The Shaykh : This is contradictory speech.

The questioner : And from here comes the strangeness.

The Shaykh : And it needs a text. Your need is...Abu Layla : Necks bow to him, and he does not exist.

The questioner : May Allah reward you with good.
