The sacred Islamic law pays significant attention to cleanliness and purity, and this attention is not limited to material aspects. The question of what is Najis (impurity) and also how to purify it is called “Taharamin al-khabath”, i.e. purity from filth. Taharah also includes spiritual aspects that might contaminate the soul, contaminations which will hinder a person from being totally directed to his/her creator.
