This is a question by a member who wishes to remain anonymous. Having a special medical wrapping around the ankles, the member could not wipe the top of his foot for wudhu all the way to the ankle joint. A relative told him just to wipe to the top of his foot, that it is not necessary to wipe all the way to the ankle joint. After some time he found out that his relative does not follow the same marja as he does. Are his previous prayers void and need to be repeated? He follows Ayatullah Sayyid Ali Khamenei.
