What should be the behaviour of a Muslim towards a non-Muslim?

The behavior of a Muslim towards a non-Muslim is guided by several principles laid out in the Qur'an and supported by hadith. The Qur'an emphasizes the importance of peace and justice in interactions with others, regardless of their faith.

In Surah Al-Hujuraat, it is stated: And if two parties of believers fall to fighting, then make peace between them. And if one party of them doeth wrong to the other, fight ye that which doeth wrong till it return unto the ordinance of Allah; then, if it return, make peace between them justly, and act equitably. Lo! Allah loveth the equitable. 49:9. This verse underscores the necessity of justice and reconciliation among believers, which extends to how they should treat others, including non-Muslims.

Moreover, the Qur'an advises that when greeted by others, Muslims should respond appropriately: When ye are greeted with a greeting, greet ye with a better than it or return it. Lo! Allah taketh count of all things. 4:86. This verse clearly indicates that a Muslim should respond to greetings from non-Muslims with kindness and respect, reinforcing a spirit of goodwill.

Additionally, the Prophet Muhammad ﷺ emphasized the importance of good character and kindness in interactions with all people. He stated: "The best of people are those who are most beneficial to others." This principle encourages Muslims to engage positively and constructively with non-Muslims.

In summary, Muslims are encouraged to behave towards non-Muslims with justice, kindness, and respect, fostering an environment of peace and cooperation.
