Q: What is
the difference between Najasah Hukmiyyah (ritual impurity without discernable characteristics) and Najasah `Ayniyyah (ritual impurity with discernable characteristics)?
Should both kinds of Najasah (ritual impurity) be removed?
Najasah `Ayniyyah is a ritual impurity that cannot be removed, such as the impurity of dogs and pigs. Najasah Hukmiyyah is a ritual impurity that causes a clean place to become impure, such as urine, stool, and other temporary impurities. This latter kind of Najasah can be removed if it and its traces of smell, taste, and color are washed with water until they disappear. (Part No. 4; Page No. 189) May Allah grant us success. May peace and blessings be upon our Prophet Muhammad, his family, and Companions.
