Water makes najis thing Pak, when the following four conditions are fulfilled:
- The water should be pure. Hence a najis thing cannot be made Pak with mixed water like rose-water, or melon-water etc. (Mudhaaf) The water should be Pak. The water should not turn into Mudhaaf while the najis thing is being washed. Furthermore, the smell, color, or taste of the najasat should not exist after the final washing, but if changes occur during earlier washings, there is no harm in it. For example, if a thing is washed with Kurr-water, or under-Kurr water and, in order to make it Pak, it is necessary to wash it twice, it will become Pak if the changes in the water do not occur in the second washing. Any changes occurring in the first washing would not matter. Small particles of Najisul Ayn should not remain behind in a najis thing after it has been washed. Other conditions for making najis thing Pak by water less than Kurr will be mentioned later.
- The interior of a najis vessel, or utensil, must be washed three times if less than Kurr water is used, and as per obligatory precaution, the same will apply if Kurr or running water is used. If a dog drinks water or any other liquid from a utensil, the utensil should be first scrubbed with Pak earth, and after washing off the dust, it should be washed twice with Kurr or lesser water. Similarly, if the dog licks a utensil, and something remains in it, it should be scrubbed with dust before washing. And if the saliva of a dog falls into the utensil, as per obligatory precaution, it should be scrubbed with dust and then washed with water three times.
- If the mouth of a utensil which a dog has licked, is narrow, dust should be thrown into it and after adding some quantity of water, it should be shaken vigorously, so that the dust may reach all parts of it. Thereafter, the utensil should be washed in the manner mentioned above.
- If a utensil is licked by a pig, or if it drinks any liquid from it, or in which a field-mouse has died, then it should be washed seven times with running water, or Kurr or lesser water. It will not be necessary to scour it with dust.
- A utensil which becomes najis because of alcoholic beverage, should be washed three times, with no difference between Kurr, lesser, and running water.
- If an earthenware has been made of najis clay, or najis water has penetrated in it, it should be put into Kurr or running water, so that wherever water reaches, it will be Pak. And if it is intended to make its interior Pak it should be left in Kurr or running water for such time, that the water would penetrate into its entire structure. And if the earthenware is moist, preventing water from reaching its inner parts, then it should be allowed to dry up, before it is put in Kurr or running water.
A najis utensil can be made Pak with under-Kurr water in two ways:
- The utensil should be filled up with water and emptied three times. Some quantity of water is poured in it, and then the utensil is vigorously shaken, so that the water reaches all najis parts before it is spilled. This should be done three times.
- If a large pot like a cauldron etc. becomes najis, it will be Pak if it is filled up with water three times, and emptied every time. Alternatively, if water is poured from above three times, in such a way that it reaches all its sides, and then the water which collects at the bottom is drawn out every time, it will become Pak. But as a recommended precaution, the vessel used for drawing out water should be washed, when being used for the second and third time.
- If najis copper and similar things are melted, and washed with water, their exterior becomes Pak.
- If a baking oven (Tannur) becomes najis with urine, and if water is poured into it once from above, in a manner that it reaches all its sides, the oven will become Pak. But as a recommended precaution, this should be done twice. And if the oven has become najis due to something other than urine, then the najasat should be eliminated first, and thereafter, water will be poured into it as described. It is better that a pit or whole is dug at the bottom, so that water collects there. That water is then drawn out, and the pit is filled with Pak earth.
- If a najis thing is immersed once in Kurr or running water, in such a way that water reaches all its najis parts, it becomes Pak. And in the case of a carpet or dress, it is not necessary to squeeze or wring or press it. And when body or dress is najis because of urine, it must be washed twice even in Kurr water.
- When a thing which has become najis with urine, is to be made Pak with water less than Kurr, it should be poured once, and as water flows off eliminating all the traces of urine, the thing will become Pak. But if dress or body has become najis because of urine, it must be washed twice so that it is Pak. When a cloth or a carpet and similar things are made Pak with water which is less than Kurr, it must be wrung, or squeezed, till the water remaining in it runs out.
- If anything becomes najis with the urine of a suckling child, who has not yet started taking solid food, and, as a precaution, is less than two years old, the thing will be Pak if water is poured over it once, reaching all parts which had been najis. As a recommended precaution, water should be poured over it once again. And if it is a carpet or dress etc. it will not be necessary to squeeze it.
