1. Kurr Water

16. Water, which fills a container whose length, breadth and depth are three spans each, is equal to a Kurr. As per precautionary measures, the dimension of the container should be three and a half spans each and its weight is twenty misqal less than hundred and twenty eight Mann[1] of Tabriz.

17. If essential Najasat like urine, blood, or anything which has become Najis, like a Najis cloth, falls in Kurr Water and if the water acquires the smell, colour, or taste of that Najasat, it becomes Najis; but if it does not change, then it is not Najis.

18. If the smell of Kurr water changes owing to something else, which is not Najis, it does not become Najis.

19. If an essential Najasat like blood etc. reaches water which is more than a Kurr, and changes the smell, colour, or taste of a part of it, if the unchanged part is less than a Kurr, the entire water becomes Najis. But if the unchanged part is one Kurr or more, then only that part which has changed the smell, colour, or taste will be Najis.

20. If the water of a fountain is connected to Kurr, the water of the fountain will make Najis water, pure (Pak). But if it falls on the Najis water drop by drop, it will not make it Pak, except when something is placed over the fountain, so that before the drops are formed, it connects to the Najis water. As per obligatory precaution, the water of the fountain should totally merge with the Najis water.

21. If a Najis object is washed under a tap which is connected with Kurr, and if water which flows from that object remains connected with Kurr, and does not contain the smell, colour, or taste of the Najasat or essential Najasat, that water will be Pak.

22. If a part of Kurr water freezes to ice, leaving a quantity which is not equal to a Kurr, and then Najasat reaches it, it will become Najis, and water obtained from the melting ice also will be Najis.

23. If the quantity of water was equal to a Kurr and later on, if someone doubts whether it has reduced to less than a Kurr, it will be treated to be equal to a Kurr, i.e. it will make a Najis object Pak, and will not become Najis if Najasat reaches it. And if water was less than a Kurr, and one suspects that it may have become equal to a Kurr, it will be not be treated as the Kurr water .

24. There are two ways of establishing that the quantity of water is equal to a Kurr:

• A person should be sure about it himself,
• Two men, who are just, should say so.

[1] Mann of Tabriz: it is a measuring scale. Each Mann is equal to 3kg of water.
