The Book of Purification - Sunan an-Nasa'i 67

"If a dog licks a vessel then wash it seven times, and rub it the eighth time with dust."

Textual Analysis

This hadith establishes the legal ruling concerning purification of vessels licked by dogs. The command is explicit and unconditional, applying to all types of vessels regardless of material.

The phrasing indicates obligation (wujub) rather than mere recommendation, as it comes in the imperative form without qualifying circumstances.

Legal Ruling & Requirements

Scholars agree the vessel becomes ritually impure (najis) through the dog's saliva. The required purification consists of seven washings with pure water.

The eighth application must be with pure, clean dust (turāb) - either rubbing the vessel with dust or mixing dust with water to create muddy water for the final cleansing.

Wisdom Behind the Ruling

Classical scholars note this ruling demonstrates Islam's emphasis on physical and spiritual cleanliness. Medical wisdom has since confirmed dogs carry harmful microorganisms in their saliva.

The specific number of washings and use of dust serve to thoroughly eliminate impurities both physically and symbolically, restoring the vessel to a state of ritual purity (tahārah).

Scope & Application

This ruling applies specifically to dogs, not other animals. The vessel must be washed even if the dog only licked a small portion of it.

If the vessel is porous and cannot be properly cleaned, it should be discarded. The ruling applies equally to cooking utensils, drinking vessels, and any container used for food or drink.
