Wiping over a wig

Is it allowed to make ablution with a wig on by only rubbing over the wig. I wear a wig and I like to keep my prayers. However it is difficult to remove the wig make ablution on my real hair. According to Islam is this allowed?

A. Here we are not going to go into the question of whether a wig is allowed in Islam or not. The question is: can we rub over the wig instead of the hair. In Islam it is not allowed to rub over a wig, either by a man or a woman. Here to rub (mash), means the water does not penetrate an area which it is obligatory to wet. According to the Shari`ah, the water must reach the scalp which a wig would prevent. Therefore it is not permitted. Similarily, it is not allowed to rub over socks, unless the socks are very thick and impermeable; because that is the requirement for rubbing over khuffs--the ankle-length leather socks which the Prophet (s) permitted for rubbing over. If the water reaches the feet by rubbing over socks, then the ablution is invalid, at which point the person must remove the socks and wash his or her feet.
