Ummah (Arabic: أمة‎) is an Arabic word meaning "community" or "nation." It is commonly used to mean either the collective nation of states, or (in the context of pan-Arabism) the whole Arab world. In the context of Islam, the word ummah is used to mean the diaspora[citation needed] or Commonwealth[citation needed] of the Believers (ummat al-mu'minin), and thus the whole Muslim world.
