ANSWER:

This is totally wrong , you must tell her that she must not make taiamum in case of availability of water, and if there is no harm on her, otherwise her prayers are not valid.

My aunt who is 65 old does not do wudoo. She just does tayammum by rubbing on clean walls where I cannot see dust. When asked to do wudoo, she says she is fearful of catching sneezing allergy (which she sometimes has). My fear is that if this is not a valid reason then her prayers would be invalid. How to make her understand?
