As-salamu alaykum. As-salamu alaykum (Arabic السلام عليكم) is an Arabic greeting often used by Muslims around the world and is widely used in the Muslim world even by non-Muslims. It nearly translates to "peace be upon you", but is often considered the equivalent to "hello", "hi" or "good day" in English. The standard response to the greeting is Wa alaykumu s-salam.
