Shiavault - a Vault of Shia Islamic Books Islamic Laws of Ayatullah Khui Purifying Things 149. There are twelve things which make impure objects pure: (i) Water (ii) Earth (iii) The sun (iv) Transformation (Istihala) (v) Change (Inqilab) (vi) Transfer (Intiqal) (vii) Islam (viii) Relation (Taba'iyat) (ix) Removal of original impurity (x) Confining (Istibra’ ) of the animal which feeds on impurities (xi) Disappearance of a Muslim, (xii) Flowing off the usual quantity of blood from the slaughtered body of the animal.
Furthermore, the smell, color or taste of the impurity should not exist after the washing after which no further washing is necessary, but if the smell, color or taste of the water changes 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 purify it, it is necessary to wash it twice, it will become pure if the color, smell or taste of the water with which it is washed for the second time does not change, even though the color, smell or taste of the water undergoes a change during the first washing.
(iv) Original impurity should not remain in the impure thing after washing it with water. There are certain other conditions also for the purification of a thing with under-Kurr water which will be mentioned later. 151. In order to purify an impure household utensil it is necessary to wash it thrice with under-Kurr water, but if it is running water or it is equal to a Kurr it is sufficient to wash the utensil only once.
However, to purify a utensil from which a dog has drunk water or some other liquid, some dust and water should be put in it in the first instance and rubbed. As a precautionary measure the dust should also be pure. Thereafter some water should be put in the utensil so that the dust is washed off. Then the utensil should be washed with Kurr water once or with under- Kurr water twice.
Similarly if a utensil has been licked by a dog it should be rubbed with dust, as a measure of obligatory precaution, before washing it.
