In order to be allowed to wipe over one’s socks, they have to have been put on at the same time, after completing wudoo’ or ghusl

What is the ruling concerning a man who washes his right foot and puts his right sock on before he washes his left foot? Is it permissible for him to wipe over his socks?

Praise be to Allah, and blessings and peace be upon the Messenger of Allah:

You cannot wipe over your socks in this case, because you put the first sock on before completing the act of purification (wudoo’ or ghusl).
