Answered by Ustadha Shazia Ahmad
Question: Assalamu alaykum
If my wife touches my paternal or maternal uncle, does it invalidate his wudu? If I touch her maternal or paternal aunt, does it invalidate her wudu?
Answer: Yes, in the Shafi`i school, it does nullify the uncle’s ritual purity in the above case. The same applies to the aunt. The ritual impurity of both parties (in both cases) is nullified, the one who touched, and the one who was touched because of the skin-to-skin to contact.
