The juridical concideration of purity(cleanliness)

Cleanliness literally means innocence and the Cleanliness rule which is one of the most famous jurisprudential rules means when there is a doubt on the cleanliness or impurity of something without considering its past condition, the jurisprudence rule says that thing is clean. There is no difference that the thing is impure naturally or the spot on it is something like blood and impure. Sometimes there is a doubt on the impurity of something naturally or the impurity of something because of a touch with an impure thing and then becomes impure. For example, if a pure shirt which is somehow wet is touched with a dry blood this shirt is still pure or not? In the mentioned rules, both things are totally pure. So, as a result if we do not know about the purity of something, that thing is pure such as the first example that we did not know about the purity of thing or like the second example when there is a doubt on the purity or impurity of something, with the help of this rule, that thing is totally clean. In this thesis, the researcher tries to explain this jurisprudence rule with clear examples based on the valid resources such as Holy Book and Sonnah.
