I was wondering some questions about najasat hopefully you can give me an answer to1. If a item that has become najjis by something that require for it to be washed more than once like pig, dog or urine, after lets say the first wash is the water that leaks off of it considered najjis if it doesnt change color? or only if it changes color? 2- If our hand becomes najjis by one of those things mentioned above and we slightly rubb them together under a tap is that suffice to say its been washed twice? 3. Is tap water connected to a kurr source considered only kurr water or flowing/running water as well?
