Rules Regarding Waters
47. Mixed water, whose meaning has been explained, does not make any Najis thing Pak, and Ghusl or Wudhu by it is void.
48. Mixed water, no matter how large its quantity may be, becomes Najis when even a small particle of Najasat falls in it. However, if mixed water or any other liquid like oil well come in contact with Najasat, whose quantity is more than standard, its Najasat is arguable. If mixed water falls on a Najis thing from above, with force, the part which touches the Najasat will become Najis, and the part which does not touch it, will remain Pak. For example, if rose water is sprinkled on a Najis hand from a sprinkler, the part which reaches the hand will be Najis and the part which does not reach the hand, will remain Pak. Similarly, in things like fountain where water is coming out with force, if the top part of it touches the Najasat it will become Najis, but the bottom part will remain Pak.
49. When Najis mixed water is mixed with Kurr or running water, in a manner that it can no longer be called mixed water, it becomes Pak.
50. Water which was originally pure and it is not known whether it has turned into mixed water, will be treated as pure, i.e. it will make Najis thing Pak and Ghusl and Wudhu with it will also be correct. But if water was originally mixed water, and it is not known whether it has turned into pure water, it will be treated as mixed water, i.e. it will not make Najis objects Pak, and it cannot be used for Wudhu or Ghusl.
51. Water about which it is not known whether it is pure or mixed, and it is also not known whether originally it was pure or mixed, will not make Najis things Pak, and it is also not permissible to perform Wudhu or Ghusl with it. However, if it is equal to or more than Kurr and a Najasat reach it, it will not become Najis.
52. When an essential Najasat like blood and urine reaches water, and changes its smell, colour, or taste, it becomes Najis even if it is Kurr or running water. However, if the smell, colour, or taste of the water changes owing to a Najasat which is outside it—for example, if a carcass, which is lying by the side of the water, causes a change in smell, the water will not become Najis.
53. If water which has become Najis due to essential Najasat like blood or urine, which changed its smell, colour, or taste, joins Kurr-water or running water, or if rain water falls on it, or is blown over it by the winds, or rain water falls on it through the drain pipe while it is raining, the water will become Pak, if the change vanishes
However, as per obligatory precaution, rain water, or Kurr water, or running water should get mixed with it.
54. If a Najis object is made Pak in Kurr or running water, the water which falls from the object after it has become Pak, is Pak.
55. Water, which was originally Pak, and it is not known whether it has become Najis, will be deemed Pak; and water, which was originally Najis, and it is not known whether it has become Pak, is Najis.
56. The leftover of a dog, a pig and a kafir is Najis, and it is Haraam to consume it. However, the leftover of the animals, whose meat is Haraam, is Pak, and it is Makrooh to eat or drink the leftover of such animals.
