Does the qalil water used to clean a najis area have to “flow?” So for example, if there was blood on my arm and it is hard to pour water over it, can I use my hand (after wetting it in the sink) to wash the area? I would do this twice. Would the water remaining on my arm be najis?
Water must reach the area at least once after removing the blood, and wiping on the hand is not sufficient. The easiest way is to place your wounded arm under the tab until it is purified.
