Ruling 371

In immersive and sequential ghusl, it is not necessary for the entire body to be pure before performing ghusl; rather, if the body becomes pure by immersing the body in water or by pouring water with the intention of ghusl, then ghusl will have taken place on condition that the water used to perform ghusl remains pure; for example, one performs ghusl with kurr water.,40

40 As mentioned in Ruling 15, as long as kurr water does not acquire the smell, colour, or taste of an impurity with which it has come into contact, it does not become impure.
