This is what we found on Wikipedia regarding the Arabic Opera: Antar & Abla:

Arabic is a Central Semitic language of the Afroasiatic language family spoken primarily in the Arab world. The International Organization for Standardization (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 is primarily made by 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 (اَلعَرَبِيَّةُ الْفُصْحَى "the eloquent Arabic") or simply al-fuṣḥā (اَلْفُصْحَى).

Arabic is the third–most widespread official language after English and French, one of six official languages of the United Nations, and the liturgical language of Islam. Arabic is widely taught in schools and universities around the world and is used to varying degrees in workplaces, governments and the media. Arabic is spoken by as many as 380 million speakers, both native and non-native, in the Arab world, making it the fifth–most spoken language in the world and the fourth–most used language on the Internet in terms of users. It also serves as the liturgical language of around two billion Muslims. In 2011, Bloomberg Businessweek ranked Arabic the fourth–most useful language for business, after English, Mandarin Chinese, and French. Arabic is written with the Arabic alphabet, an abjad script that is written from right to left.

During the Middle Ages, Arabic was a major vehicle of culture and learning, especially in science, mathematics and philosophy. As a result, many European languages have borrowed words from it. Arabic influence, mainly in vocabulary, is seen in European languages (mainly Spanish and to a lesser extent Portuguese, Catalan, and Sicilian) owing to the proximity of Europe and the long-lasting Arabic cultural and linguistic presence, mainly in Southern Iberia, during the Al-Andalus era. Maltese is a Semitic language developed from a dialect of Arabic and written in the Latin alphabet. The Balkan languages, including Albanian, Greek, Serbo-Croatian, and Bulgarian, have also acquired many words of Arabic origin, mainly through direct contact with Ottoman Turkish. Arabic has also influenced other languages across the globe throughout its history, especially languages where Islam had a historic presence. The most markedly influenced languages are Persian, Turkish, Hindustani (Hindi and Urdu), Kashmiri, Kurdish, Bosnian, Kazakh, Bengali, Malay (Indonesian and Malaysian), Maldivian, Pashto, Punjabi, Armenian, Azerbaijani, Sicilian, Tagalog, Sindhi, Odia, Hebrew and African languages such as Hausa, Bambara, Amharic, Tigrinya, Somali, Tamazight, and Swahili. Conversely, Arabic has borrowed some words (mostly nouns) from other languages, including its sister-language Aramaic, Persian, Greek, and Latin and to a lesser extent and more recently from Turkish, English, French, and Italian.

Classical Arabic (and Modern Standard Arabic) is considered a conservative language among Semitic languages; it preserved the complete Proto-Semitic three grammatical cases and declension (ʾiʿrāb), and it was used in the reconstruction of Proto-Semitic since it preserves as contrastive 28 out of the evident 29 consonantal phonemes.
