Other salafi brothers of AllahKaBanda will not agree with his interpretation or definition of bidet or innovation. Also the hadees being quoted is not specific to religious matters either.
To carry your point across.
We had an open house in Ramadan for your neighborhood non muslim friends one of the question asked by one of the guests was " Why you guys take your shoes off before entering home and expect your guests to do so. Is it part of the religion ?"
