question #1 Sahih Muslim 372, Book 3, Hadith 146 : What is the significance of physical cleanliness in Islam, especially after certain activities?

The Messenger of Allah (ﷺ) happened to meet him and he was (sexually) defiled, and he slipped away and took a bath and then came and said: I was (sexually) defiled. Upon this he (the Holy Prophet) remarked: A Muslim is never defiled.
