Question 31: The wall of my house has become najis (impure). Can I make it clean by simply removing the impurity and pouring kurr water once on the najis part of the wall? Would it be sufficient?

Question 8: Most modern washing machines automatically cycle through various operations until the clothes are completely washed, rinsed, and partially dried. Do they make najis things ritually pure? If they do not become taher, what about the drum? Does it become najis and is it necessary to rinse it?
