Classical Arabic works refer to literary, philosophical, and scientific texts produced in the Arabic language from the 7th to the 19th centuries. These works include poetry, prose, and religious texts, with notable contributions from scholars like Al-Farabi, Ibn Sina, and Al-Ghazali. They played a crucial role in preserving and advancing knowledge in various fields, including mathematics, medicine, and astronomy. The Quran is the most significant classical Arabic work, serving as the holy book of Islam. Other important texts include One Thousand and One Nights, a collection of folk tales, and the writings of Ibn Khaldun, who is known for his contributions to sociology and historiography. These works continue to influence modern Arabic literature and thought.
