Confused about whether dogs are ritually impure in Islam? This concise guide walks through the Qur’an, key hadiths and mainstream juristic positions so you know what to do in everyday cases.
The impurity of dogs is an important topic in Islamic jurisprudence and religious culture. It matters for everyday practices in many Muslim communities. Najāsah (impurity) means lack of ritual purity and uncleanliness.
The Qur’an does not explicitly state that dogs are impure, but some verses relate to matters of purity and dietary or ritual distinctions. For example, Sūrat al-Māʼidah (5:4) divides lawful and unlawful animals in certain contexts. That verse does not mention dogs directly on the question of impurity, but it underlines the importance of purity and cleanliness in Islam.
In the Prophetic and hadith literature there are clear references that have been understood to indicate canine impurity. One well-known hadith reported in collections such as Muslim states, for example, that if a dog drinks from your vessel you must wash the vessel. This narration is taken as evidence of the dog’s effect on ritual purity of containers.
These reports shape the traditional juristic rulings concerning dogs and their impact on people and objects used for worship.
Islamic jurists have differed on the issue, but the majority of both Shia and Sunni jurists consider dogs ritually impure and hold that contact with them renders the person or objects impure. At the same time, some classical jurists offered different views, and a few contemporary scholars have argued for contextual readings.
Shia jurists generally affirm the impurity of dogs and consider contact with them to affect ritual purity. For instance, in his work Tahrir al-Wasilah, Ayatollah Khomeini discusses the dog’s impurity and prescribes avoiding contact in contexts where ritual cleanliness matters.
Many Sunni jurists likewise emphasize dogs’ impurity, though there have historically been variations — for example, Abu Hanifa’s school is sometimes understood to hold a different stance about the dog’s impurity. These differences have created varying social practices across Muslim communities.
Scholars cite several grounds for the ruling that dogs are impure:
Hadith evidence: Numerous reports attributed to the Prophet and his household are cited as primary textual evidence that dogs affect ritual purity.
Nature and behavior: Some jurists point to certain characteristics and habits of dogs as a justificatory reason for classifying them as impure.
Protection of ritual purity: A central concern of the rulings is safeguarding ritual cleanliness, especially before acts of worship such as prayer.

The impurity of dogs is a significant and sensitive issue in Islamic law, founded on hadith reports and juristic reasoning rather than a direct Qur’anic prohibition. While the majority of classical jurists across Sunni and Shia schools have treated dogs as ritually impure and have prescribed purification steps after contact, there are historical nuances and minority positions. Contemporary discussions sometimes revisit earlier rulings in light of changing social circumstances and scientific considerations, but traditional practice and the concerns for ritual purity remain influential in shaping Muslim households’ attitudes toward dogs.
