If a part of Kurr water freezes and the remaining water is not equal to a Kurr and impurity reaches it, it becomes impure and the quantity of ice which melts and becomes water also becomes impure. 23. If the quantity of water is equal to a Kurr and later one doubts whether it has become less than a Kurr it will be treated to be equal to a Kurr i.e. it purifies an impure thing and does not become impure if an impurity (Najasat) reaches it.
And if water was less than a Kurr and one doubts whether it has become equal to a Kurr it will be treated as under-Kurr water. 24. There are two ways for deciding that the quantity of water is equal to a Kurr: (i) A person should be sure about it personally and (ii) Two men who are just should say so. And it is not unlikely that the word of one just man and even of a reliable person in this behalf should be sufficient. Under-Kurr Water 25.
Under-Kurr water means water which does not spring up from the earth and its quantity is also less than a Kurr. 26. If under-Kurr water is poured on something which is impure it becomes impure, or if an impure thing contacts it, it becomes impure. However, if such water falls on an impure thing from above, only that part of it which contacts it will become impure, and the water above it will be pure (Tahir). 27.
Under-Kurr water which is thrown on something to remove the original impurity (Najasat) from it and gets separated from it is impure. However, the under-Kurr water which is thrown on a thing to purify it after the original impurity has been separated from it will be pure after getting separated from it provided that the place of impurity is purified immediately after water is thrown on it.
For example if the place of impurity is a thing which becomes pure after washing once and does not also contain an original impurity its washed out water i.e. the water which gets separated from it at the time of washing is pure. However, if a thing must be washed twice, then on the basis of obligatory precaution, its first washed out water should be considered impure, and the washed out water of its second washing is pure. 28.
The water with which the outlets of urine and stool are washed is pure subject to the following five conditions: (i) It does not have the smell, color or taste of the impurity. (ii) An impurity has not reached it from outside. (iii) Any other impurity like blood has not come out with urine or stool. (iv) Particles of stool do not appear in the water.
