Purity: Is Caution Over Minute Fibers from Najis Clothes Necessary?

English:

Question #288:

Minute hair-like fibers fall off from every dress and pieces of cloth, and we find these minute fibers if we observe the water in a washtub while washing clothes. Accordingly, when the washtub is full of water and connected with tap water, by immersing clothes in it the water overflows from its sides. Due to the presence of these minute fibers in the overflowing water, as a caution I clean the whole place. Or when I take off the children’s najis clothes I wash the place where these clothes were taken off even if it is dry, because I think those minute fibers have fallen there. Is observing such cautions necessary?

Answer #288:

If a cloth is put into a washtub for washing and a tap water flows on it until it is completely soaked with water and then the water separates from the cloth or moves within the cloth, the water in the washtub, the cloth, and the washtub are pure, as well as the minute fibers that have fallen from the clothes, in the question, and overflow along with the water. Also dust and minute fibers that are separated from a najis cloth are considered pure unless you are sure that they have been separated from the najis parts of the cloth and it is not necessary to observe caution in case of doubt whether they originally had been separated from najis clothes or not and whether or not their place is najis.
