If one wears a leather sock over a leather sock, then wipes over them, what is the ruling?

Question:
Honorable Shaykh, may Allah grant you success, he says: If one wears a leather sock over a leather sock, then wipes over them.

Answer:
If one wears a leather sock over a leather sock, and both socks are covering and suitable for wiping over, then if he wipes over the lower one before wearing the upper one, the wiping remains valid on the lower one. And if he did not wipe over the lower one and began the wiping on the upper one, he wipes over the upper one. So the criterion is the beginning of the wiping on either of them.
