Purity: Purification of Food Items and Cloth in Utensils with Water
Practical Laws of Islam as per the teachings of Ayatullah Sistani
Ruling 160
If the exterior of rice, meat, and suchlike becomes impure, in the event that it is placed in a pure bowl or something similar, and water is poured over it once and emptied, it becomes pure. If it is placed in an impure utensil, this procedure must be carried out three times for the utensil to become pure. If a person wants to place a cloth or something similar that needs to be squeezed in a utensil and wash it with water, he must squeeze the object each time water is poured over it and tilt the utensil so that the remaining water that has gathered pours out.
