Question: Assalam alaykum
For a long time I used to clean my floor with a wet mop using the same water for the whole floor.
I have found out that the inner sole of a pair of my shoes was made from pig skin leather.
When I just cleaned the floor of my rooms would the impurity of the shoes render the whole floor of my rooms impure?
Answer: Assalamu alaikum wa rahmatullah,
No, the floors of your home are not impure, and you don’t need to take any measures to clean them.
There are two issues here:
1. It is generally impermissible to benefit from any part of a pig. If you own some footwear containing some kind of inner sole or lining made of pig leather, that area of the shoe would be ritually filthy, yet not the entire shoe.
2. The mere presence of something ritually filthy doesn’t make another thing filthy. Rather, there are principles dictating filth transfer, and in this case, a wet foot coming into contact with a dry sole would not affect the purity of the foot as long as the traces of impurity were not manifest [on the foot].
