When does wiping over the socks begin, after the state of ritual impurity or before it?

The questioner:
Does the period for wiping over the socks begin after the state of ritual impurity, or if one starts wiping over the leather socks before the state of ritual impurity, does the period begin then?

The Shaykh:
Wiping is done before the state of ritual impurity. Wiping only occurs after the ablution is broken. As for before the ablution is broken, he remains in his original state of ritual purity and does not need to wipe. Yes.

The presenter:
May Allah reward you.

The Shaykh:
Wiping does not occur except after the ablution is broken. Yes.
