Purity: Purification of Meat, Fat, and Greasy Surfaces with Water

Practical Laws of Islam as per the teachings of Ayatullah Sistani

Ruling 169

Meat or fat that has become impure is washed with water like any other object. The same applies if the body, clothing, or a utensil has a little fat on it that does not prevent water from reaching it.
