Can we wish non-Muslims "happy holi", "happy Diwali", etc.?

In addressing whether Muslims can wish non-Muslims "happy Holi," "happy Diwali," or similar greetings, Islamic teachings emphasize the importance of responding to greetings in a manner that reflects kindness and respect.

The Qur'an states, 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 encourages Muslims to reciprocate greetings, highlighting the importance of good manners and maintaining positive relationships.

Regarding specific greetings for non-Muslim festivals, while the general principle is to respond kindly, scholars differ on the appropriateness of wishing non-Muslims well on their religious occasions. Some scholars believe it is permissible to offer greetings that express goodwill, while others caution against participating in non-Islamic celebrations.

In support of this, there are narrations from the Prophet Muhammad ﷺ that guide how to respond to greetings from non-Muslims. For instance, it is reported that when the People of the Book greet Muslims, they should respond with And upon you Sunan Abu Dawud 43:435SunniSahih (per Al-Albani), indicating a respectful acknowledgment without endorsing the specific celebration itself.

Thus, while it is generally acceptable to wish non-Muslims well in a way that expresses goodwill, caution and consideration of the context are advised.
