Muslims should greet each other with the phrase **”As-salamu Alaikum”** (Peace be upon you). This greeting can be enhanced by saying **”Wa Rahmatullahi wa Barakatuh”** (and the mercy and blessings of Allah) for a more complete and respectful greeting.

The response to this greeting is **”Wa Alaikum as-Salam”** (And upon you be peace), or **”Wa Alaikum as-Salam wa Rahmatullahi wa Barakatuh”** to reciprocate fully.

This greeting fosters peace, kindness, and goodwill within the community, reflecting Islamic values of respect and brotherhood.
