What hadith supports Muslims not buying haram / non halal products?

There are several hadiths and Qur’anic verses that emphasize avoiding haram (forbidden) substances, maintaining purity, and ensuring that what one consumes or possesses is lawful (halal). These principles can be applied to purchasing halal pet food as well.

• The Importance of Halal & Tayyib (Pure) Sustenance

The Prophet ﷺ said: “Indeed, Allah is pure and He loves purity. He is clean and loves cleanliness. He is generous and loves generosity. He is hospitable and loves hospitality.”
(Sahih Muslim 91)

Application: Since Islam encourages purity in all aspects of life, avoiding haram ingredients (such as pork, non-halal meat, and carrion) extends to what we bring into our homes—including pet food.

• Avoiding Haram & Doubtful Matters

The Prophet ﷺ said:“That which is lawful is clear, and that which is unlawful is clear, and between the two of them are doubtful matters about which many people do not know. Thus, he who avoids doubtful matters clears himself in regard to his religion and his honour.”
(Sahih al-Bukhari 52, Sahih Muslim 1599)

Application: Many commercial pet foods contain haram ingredients, making them doubtful in Islamic law. To stay on the safe side, choosing certified halal pet food removes any uncertainty.

• The Prohibition of Dealing with Haram Substances

The Prophet ﷺ said: “When Allah forbids something, He also forbids its price.”
(Sunan Abi Dawood 3488, Ahmad 2719 – Hasan)

 Application: If a product contains haram ingredients (such as pork or non-halal meat), purchasing it indirectly supports the haram industry. Choosing halal pet food ensures that your money is spent on ethical, permissible goods.

• The Command to Avoid Impurity (Najasah)

The Prophet ﷺ said: “A believer does not become impure.”
(Sahih al-Bukhari 283, Sahih Muslim 371)

Application: If a pet consumes haram food and then licks its owner, some scholars believe this could spread impurity (najasah). By feeding pets halal-certified food, this concern is eliminated.

• The Responsibility of Every Muslim in Their Actions

The Prophet ﷺ said:“Each of you is a shepherd, and each of you is responsible for his flock.”
(Sahih al-Bukhari 893, Sahih Muslim 1829)

Application: This hadith highlights the responsibility of caretakers—including pet owners. Just as Muslims ensure their own food is halal, they should also ensure their pets’ food aligns with ethical and halal principles.

• Conclusion

These hadiths emphasize the importance of consuming and dealing only with halal products, maintaining purity, and avoiding anything doubtful or haram. Since halal pet food is now available, Muslims can make a conscious choice to align their pet’s diet with Islamic values
