Is it suffienct to wash wadi and madhi by taking a handful of water and putting it over it? Before I used to just wipe them off with wet hands until no more whiteness remains is that wrong?
If you are referring to your private part, this would be sufficient.
But if the impurity is on your clothes, you need to wash impurities off and squeeze it until it is gone.
With mathi, sprinkling it with water and running it over it is sufficient.
