Ruling 153 — Purification (Ṭahārah)

If an impure object is immersed once in kurr or flowing water such that water reaches all its impure areas, it becomes pure. In the case of a rug, clothing, or a similar thing, it is not necessary to squeeze or wring it or stamp on it. Furthermore, in case a person’s body or clothing becomes impure with urine, then based on obligatory precaution, it is necessary to wash it twice with kurr water and the like; however, if flowing water is used, it becomes pure by washing it once.
