The Hejaz is a region that includes the majority of the west coast of Saudi Arabia, covering the cities of Mecca, Medina, Jeddah, Tabuk, Yanbu, Taif and Baljurashi. It is thus known as the "Western Province", and it is bordered in the west by the Red Sea, in the north by Jordan, in the east by the Najd, and in the south by the Region of 'Asir. Its largest city is Jeddah, which is the second-largest city in Saudi Arabia, with Mecca and Medina, respectively, being the fourth- and fifth-largest cities in the country.

Arabic is a Central Semitic language of the Afroasiatic language family spoken primarily in the Arab world. The ISO assigns language codes to 32 varieties of Arabic, including its standard form of Literary Arabic, known as Modern Standard Arabic, which is derived from Classical Arabic. This distinction exists primarily among Western linguists; Arabic speakers themselves generally do not distinguish between Modern Standard Arabic and Classical Arabic, but rather refer to both as al-ʿarabiyyatu l-fuṣḥā or simply al-fuṣḥā (اَلْفُصْحَىٰ).
