Why is dogs saliva considered Haram in Islam?

In Islam, the saliva of dogs is generally considered impure, leading to specific rulings regarding cleanliness and the handling of utensils that a dog may have licked. This perspective is derived from various hadith.

One important narration states: The Messenger of Allah (peace be upon him) commanded the killing of dogs, then he said, 'What is with them?' Then he allowed the hunting dog and the sheepdog, and said: 'If a dog licks the utensil, wash it seven times, and cleanse it the eighth time with soil.' Sahih Muslim 2:119SunniSAHIH. This hadith illustrates that the saliva of dogs is treated with caution, requiring thorough cleaning of any utensils they may have licked.

Additionally, a narration in Al-Kafi mentions, The Messenger of God (peace be upon him and his family) said, 'Dogs are among the weak jinn. So if any of you eats and there is some food in front of him and a dog is present, he should feed it or drive it away, for they have evil spirits.' Al-Kafi 9:101ShiaDa'if على المشهور. This statement further emphasizes the belief in the impurity associated with dogs and their saliva.

According to Sunni scholarship, as reflected in Tafsir Ibn Kathir, the general guidance on cleanliness and the treatment of dogs stems from the need to maintain ritual purity in Islamic practice. Shia scholars also acknowledge the concerns surrounding dogs and their saliva, viewing them as impure creatures whose presence can affect cleanliness and purity in a household.
