“If one wants to purify such clothes with pure water which is connected to a kurr source [e.g., under the water tap or by using a hose pipe], even then it is necessary to wash them twice. Similarly, it is necessary to wash the body twice -even when washed in kurr water- while purifying if it has become najis because of urine.” Does this also apply to a toilet seat that has gotten urine on it? Like would you have to wash it twice?
The ruling of washing twice is specific to purifying the body and clothes from urine, all other things including the toilet seat can be washed once provided that the impurity is removed.
