<P> Aside from the theological viewpoint, Islam is historically believed to have originated in the early 7th century CE in Mecca, and by the 8th century the Umayyad Islamic caliphate extended from Iberia in the west to the Indus River in the east . The Islamic Golden Age refers to the period traditionally dated from the 8th century to the 13th century, during the Abbasid Caliphate, when much of the historically Muslim world was experiencing a scientific, economic and cultural flourishing . The expansion of the Muslim world involved various caliphates and empires, traders and conversion to Islam by missionary activities (dawah). </P> <P> Most Muslims are of one of two denominations: Sunni (75--90%) or Shia (10--20%). About 13% of Muslims live in Indonesia, the largest Muslim - majority country, 31% in South Asia, the largest population of Muslims in the world, 23% in the Middle East - North Africa, where it is the dominant religion and 15% in Sub-Saharan Africa . Sizeable Muslim communities are also found in the Americas, the Caucasus, Central Asia, China, Europe, Mainland Southeast Asia, the Philippines, and Russia . </P> <P> Islam (Arabic: الإسلام ‎, IPA: (alʔɪsˈlaːm) (listen)) is a verbal noun originating from the triliteral root S-L-M which forms a large class of words mostly relating to concepts of wholeness, submission, safeness, and peace . In a religious context it means "voluntary submission to God". Islām is the verbal noun of Form IV of the root, and means "submission" or "surrender". Muslim, the word for an adherent of Islam, is the active participle of the same verb form, and means "submitter" or "one who surrenders". The word sometimes has distinct connotations in its various occurrences in the Quran . In some verses, there is stress on the quality of Islam as an internal spiritual state: "Whomsoever God desires to guide, He opens his heart to Islam ." Other verses connect Islām and religion (dīn) together: "Today, I have perfected your religion (dīn) for you; I have completed My blessing upon you; I have approved Islam for your religion ." Still others describe Islam as an action of returning to God--more than just a verbal affirmation of faith . In the Hadith of Gabriel, islām is presented as one part of a triad that also includes imān (faith), and ihsān (excellence). </P> <P> Islam was historically called Muhammadanism in Anglophone societies . This term has fallen out of use and is sometimes said to be offensive because it suggests that a human being rather than God is central to Muslims' religion, parallel to Jesus Christ in Christianity . Some authors, however, continue to use the term Muhammadanism as a technical term for the religious system as opposed to the theological concept of Islam that exists within that system . </P>
