Muslim is the name of a religion, as Christianity and Judaism are names of religions. The Arabic word “Islam” is based on the root “slm,” which means peace or surrender to God. Combining both translations results in the combined meaning “the state of peace through following God’s guidance.”
Islamic is an adjective that modifies a non-human noun, as for example, “Islamic art,” “Islamic architecture,” “Islamic beliefs,” etc. This term should not be used to refer to a person.
A follower of Islam is called a Muslim, or “one who is in a state of peace by following God’s guidance.”
While the term Arab has been used in the past to refer to members of a Semitic ethnic group from the Arabian Peninsula, today the word “Arab” refers to people from Arabic-speaking countries, most of which are in the Middle East and North Africa. The term Arabian was historically used to describe an inhabitant of the Arabian Peninsula. Today “Arabian” is used as an adjective to describe a non-human noun (e.g., Arabian coffee); it should not be used to refer to people.
