Washing one foot and wearing the leather sock, then washing the other

Question:
If one washes his right foot, then puts on the sock, then washes his left foot, then puts on the sock, is his wudu' or his wiping valid?

Answer:
No, because you have heard that one must put them on after completing the state of purity. If one washes only one foot, the state of purity is not complete. The Prophet (peace and blessings be upon him) said: This indicates that it is necessary to wash both feet before putting them into the leather socks. So if one washes one foot and puts on the sock, then washes the other foot and puts on the sock, he does not wipe over them, because he did not put them on after completing the state of purity.
