Ruling on wearing the right sock before washing the left foot

Question:
If he performs wudu, washes his right foot, and wears the sock over it, then washes his left foot and wears the sock over it?

Answer:
There is scholarly disagreement among the scholars on this: some permit this; wearing the right sock, then washing the left foot and wearing the sock over it. A group of scholars say that he wipes; because he wore this one in a state of purity, and this one in a state of purity, but the first one was not complete purity, yet it is in the meaning of complete purity.
However, what is better for the believer in such a case is to avoid the disagreement. So if he washes the left foot and finishes with it, and has already worn the right sock, he takes it off, then puts it back on; so that the disagreement does not remain, and no difficulty arises; so that the wearing of both is in a state of purity, so that he is safe from the disagreement.
