Question Summary

How does one purify themselves from the saliva of a dog? How does impurity transfer?


In the Name of Allah, the Most Merciful and Compassionate

I’m sorry to hear about your difficult situation. I pray that Allah Most High eases for you all your difficulties.

I want to preface my answer to your question by mentioning a key verse of the Qur’an, which should always be at the forefront of our minds.

Allah Most High says, “…Allah intends ease for you, not hardship,…” [Qur’an; 02:185]

Most of those we have encountered in a similar circumstance as yourself find Islam difficult due to a lack of knowledge. As one increases in the knowledge and understanding of Islam, the easier and clearer the religion becomes.

The Answer

A dog’s saliva is impure and must be washed; however, washing seven times, once with soil, is not an obligation. It suffices that one washes the saliva off once. [Tahtawi,Shurunbulali; Hashiyat Maraqi al-Falah]

With that being said, just because a dog may have licked you or your clothing does not mean your entire house is impure.

Only the place which the dog licked is impure.


Please consider taking classes in basic Islamic law. Learning the rulings of purification and prayer will greatly help you.

Consider the Islamic Studies Curriculum:

Allah Most High is not a tyrant waiting to punish us for every minor mistake.
Allah Most High says, “Your Lord has taken upon Himself to be Merciful…” [Qur’an; 06:54]

Hope this helps
Allah knows best
