Arabic numerals
The first mentions of the numerals in the West are found in the "Codex Vigilanus" of 976.
History of the Arabic alphabet
Since the early 20th century, as the Ottoman Empire collapsed and European influence increased, many non-Arab Islamic areas began using the Cyrillic or Latin alphabet, and local adaptations of the Arabic alphabet were abandoned. In many cases, the writing of a language in Arabic script has become restricted to classical texts and traditional purposes (as in the Turkic States of Central Asia, or Hausa and others in West Africa ), while in others, the Arabic alphabet is used alongside the Latin one (as with Jawi in Brunei).
