Does touching dry impurity with wet hands make me impure?
If I touch something that has a wet impurity (ex. unrine) on it but it dries, then it becomes wet again during the time of touching with my hand. Do I need to clean my hands?
Or suppose someone pee'd on my bag but it dried later, then the impure part became again and I touched the wet bag with my hand, so do I need to clean my hand before praying?
Note: Dry impurity can't make someone impure.
