Flowing water is that water which springs forth from the earth and then flows, like the water of a spring or a canal.
29. If najÁsah comes in contact with flowing water, even if it be less than kurr, as long as its smell, colour or taste does not change, it is ÔÁhir.
30. If najÁsah comes in contact with flowing water, only the portion whose smell, colour or taste changes due to the najÁsah is najis. The side which is connected to the spring is ÔÁhir, even if it be less than kurr. Similarly, the water on the other side of the stream will be ÔÁhir if it is equal to kurr, or if it is connected to the water near the spring through unchanged water. If not, it is najis.
31. The water of a spring which does not flow, but replaces water every time water is drawn from it, will be treated as flowing water. This means that if it comes in contact with najÁsah, it is ÔÁhir as long as its smell, colour or taste does not change.
32. If water at the bank of a canal is stationary, but is connected with flowing water, and upon contacting a najis object its smell, colour or taste does not change, it does not become najis.
33. If a spring is active in winter, but remains dormant in summer, it will be treated as flowing water only when it is active.
34. Even though the water of the pool in a bath may be less than kurr, it will be treated as flowing water as long as it is connected to a source whose water is equivalent to kurr.
35. The water from the pipes fitted in bathrooms and buildings, pouring through taps and showers, will be treated as flowing water if it is connected to a tank holding water which is not less than kurr.
36. Water which flows on the ground but does not gush out from the earth, will become najis upon contacting najÁsah if it is less than kurr. However, if the water flows with force and najÁsah contacts its lower end, the upper end will not become najis.
