What is the importance of Arabic language? They are part of the Arab World because the largest religion in the region is Islam. Arabic is very important in Islam because Muslims believe that Allah (God) used it to talk to Muhammad through the Archangel Gabriel (Jibril), giving him the Quran in the language. Many but not all Arabic-speakers are Muslims. Its graceful script, magnificent style and rich vocabulary give the language a unique character and flavour. Arabic is the largest member of the Semitic language family, which also includes languages like Hebrew and Aramaic. Like most other Semitic languages, Arabic is written from right to left.
