How can it be determined whether the impurity found on clothes is tangible or not? And what is the ruling if impure clothes are placed in the washing machine without removing the tangible impurity? And does washing with water and soap absolutely purify according to the mentioned madhhab, whether the water and soap come into contact with the impurity or vice versa? And if this opinion is adopted along with the Maliki opinion that the washing machine water does not become impure unless it changes, will the clothes be purified and the water and soap remain pure as long as they do not change?

The persistence of the impurity's substance is known by the presence of one of its characteristics (color, taste, smell). If the impurity's substance is removed by any means, the place becomes pure, because the removal of impurity aims to remove the offensive characteristic. Sheikh Ibn 'Uthaymeen holds that water does not become impure except through change [in its characteristics]. So, if the impurity's substance is removed from clothes washed with water, they have become pure. However, it is more cautious to pour water over the impure garment to avoid the difference of opinion of those who believe that a small amount of water becomes impure upon the arrival of an impurity, even if its characteristics do not change.
