The plank or slab of stone on which a dead body is given Ghusl, and the cloth with which his private parts are covered, and the hands of the person who gives Ghusl and all things washed together with the dead body, become Tahir when Ghusl is over. 100.When a person washes something with water to make it Tahir, his hands washed along with that thing, will be Tahir when the thing is Tahir. If cloth etc.

Is washed with under-Kurr water and is squeezed as usual, allowing water to flow off, the water which still remains in it is Tahir. When a Najis utensil is washed with under-Kurr water, the small quantity of water left in it after spillig the water of final wash, is Tahir. IX. Remoral of Najis-ul ‘Ayn If body of an animal is stained with a Najis-ul-Ayn like blood or with something which has become Najis, for example, Najis water, its body becomes Tahir when the Najasah disappears.

Similarly, the inner parts of the human body, for example inner parts of mouth, or nose or inner ears which become Najis with an external Najasah,become Tahir, after the Najasah has disappeared. But the internal Najasah, like the blood from the gums of the teeth,does not make inner mouth Najis. Similarly, any external thing which is placed internally in the body,does not become Najis when it meets with the internal Najasah.

So if the dentures come in contact with blood from the gums, it does not require rinsing. Of course, if it contacts a Najis food, it must be made Tahir with water. If food remains between the teeth, and blood emerges within the mouth, the food will not be Najis if it comes in contact with that blood. Those parts of the lips and the eyes which overlap when shut, will be considered as inner parts of the body, and they need not be washed when an external Najasah reaches them.

But a part of which one is not sure whether it is intenal or external, must be washed with water if it meets with an external Najasah. X. Istipa’ of an animal which Eats Najasah The dung and urine of an animal which is habituated to eating human excrement,is najis, and it could be made Tahir by subjecting it to "Istipà", that is, it should be prevented from eating Najasah, and Tahir food should be given to it,till such time that it may no more be considered an animal which eats Najasah.
