Question: Whether wudu will break if i touch my wife. Also clarify, what about when i touch non-muslims ?
Answer: Wa alaikumussalaam va rahmatullahi vabarakathuhu, Aap ka sawaal mousool huwa Jawaab hazir hai:
Indal Ahnaaf, When you touch your wife wuzu will not break. Whereas, for Shawafe it will break ( if you are Shafi ask your Shafi Imaam)
Even when you touch non-muslims it will not break.
Allahu alam va Rasoolullah alam azzawajalla va sallallahu alaihiwasalam.
