The Effect of a Person Newly Woken Dipping a Hand into a Small Quantity of Water
Does the status of a small quantity of water change when someone newly woken from the night's sleep dips a hand into it before washing it?
The water is not made impure by the dipping of the hand, and it does not become used water if he put the hand in to scoop, out of need; if he put it in for some other purpose than scooping, the water becomes used.
The water is not made impure by that unless an impurity on the hand is established, so it remains purifying.
The water does not become used water by the dipping of the hand, so it remains purifying and lifts ritual impurity.
The small quantity of water becomes pure but no longer purifying — it does not lift ritual impurity — once the hand is dipped in it before being washed three times.
