Running water, such as that of rivers, tributaries, streams, and springs. 4. Rainfall. These are the immunized waters. * What then are waters that are not immunized? - These are waters found in small reservoirs, utensils, bottles, tumblers, etc. that are stagnant, apart from well water that is less than kurr, and that which is termed “little water”. By now, you know they become najis on contact with najis things. * What about diluted water?
Moreover, when “abundant water” is connected to “little water”, the latter can be regarded as abundant whereby it remains immunized as long as it is fed from an abundant source of water. To give you some examples, your domestic storage tank that is normally connected to water mains supply becomes abundant; likewise, if you placed a bowl or a saucepan under the running water of a sink tap, the water in it becomes abundant, and so on. That is, as long as the water remains running. * Fine.
What, if a drop of blood falls in the water of a tank the size of a kurr, that is not connected to the mains? - It will not become najis, unless blood keeps dripping that the colour of the water changes to yellowish, for example. * What, if it falls in a small plate? - It will render it najis. * What, if we turn the tap on, thus restoring the original purity of the water? - The water in the plate will become tahir. [However, it will become najis again, if you turn the tap off.
This is because, if the plate becomes najis, it becomes tahir only when it is washed three times], as shall be explained to you later. * If we were to pour water from a pitcher, or watering can, onto something najis, does the water become najis? - No, because najasah does not climb the water column. Accordingly, neither the cascading water nor the water in the can becomes najis. * How would rain water render najis things tahir?
