najis clothes that are washed by regular washing machines become pure and so do the machines. These machines wash clothes once or twice using detergent and after the impurity has been removed, they wash the clothes with pure water and then empty the water. In order to purify rugs and carpets that are glued to the ground, first of all the najis substance must be removed. Then if the water is Qalīl less than Kurr, some of it must be poured over the impure spot in such a manner that it covers it and the water must be moved a little and then it must be collected using a piece of cloth. However, the piece of cloth and the bowl of water must be washed later as they have become najis too. But if you wash them with tap water, it will suffice if you make the water reach the najis spot and cover it and then move it a little to make it ṭāhir.
