3. Running Water

31. Running water is the water, which springs forth from the earth and then flows, like the water of a natural spring or Ghanat (subterranean canal).

32. Running water, even if it is less than Kurr, does not become Najis upon contact with Nejasat; unless its smell, color or taste changes due to that Nejasat.

33. If Nejasat reaches the running water, only the part of the water will be Najis whose smell, color or taste changes on account of it, and that end which is connected with the spring will be Pak even if it may be less than a Kurr. Also, the water on the other side of the spring will be Pak, if it is equal to a Kurr, or if it is connected with the water near the spring through unchanged water. If not, then it would be Najis.

34. The water of a spring which does not flow, but replaces water every time that water is drawn from it; if it is in contact with Nejasat, it will be Pak unless its smell, color or taste changes because of that Nejasat.

35. The water which is stationary at the bank of a canal but it is connected to the flowing water, if Nejasat reaches, it will be Pak unless its smell, color or tastes changes because of that Nejasat.

36. If a spring is active in winter, but remains dormant in summer, it will be treated as running water only when it is active.

37. If the water in a pool is less than Kurr, but it is connected to a store of water, which is equal to one Kurr, it is treated like running water.

39. The water, which flows over the ground but does not spring forth, if it is less than Kurr and Nejasat reaches it, it will turn to Najis. But if it is poured form above and, the upper part will not be Najis because of a Nejasat, which reaches the lower part.
