Purity: Ruling on Purifying Utensils Contaminated by Impurities or Dogs

Practical Laws of Islam as per the teachings of Ayatullah Sistani

Ruling 144

The impure inside of a utensil must be washed three times with qalīl water. Similarly, [it must be washed three times] with kurr, flowing, or rainwater, based on obligatory precaution. A utensil that a dog has licked or drank water or some other liquid out of must first be scrubbed with pure soil; then, that soil must be discarded and the utensil washed twice with qalīl, kurr, or flowing water. If a dog’s saliva falls into a utensil or its sweat, urine, or excrement touches the inside of it, or if a wet part of a dog’s body touches the inside of a utensil, then based on obligatory precaution, the utensil must first be scrubbed with soil and then washed three times with water. If a dog licks something other than a utensil, such as a person’s hand, the rule for utensils does not apply and scrubbing it with soil is not necessary; instead, washing it once is sufficient.
