Where did Arabic language come from?

Answer 1

Arabic language came from Semitic Language

The earliest surviving texts in Proto-Arabic, or Ancient North Arabian, are the Hasaean inscriptions of eastern Saudi Arabia, from the 8th century BC, written not in the modern Arabic alphabet, nor in its Nabataean ancestor, but in variants of theepigraphic South Arabian musnad. These are followed by 6th-century BC Lihyanitetexts from southeastern Saudi Arabia and the Thamudic texts found throughout Arabia and the Sinai, and not actually connected with Thamud. Later come theSafaitic inscriptions beginning in the 1st century BC, and the many Arabic personal names attested in Nabataean inscriptions (which are, however, written in Aramaic). From about the 2nd century BC, a few inscriptions from Qaryat al-Fāw (nearSulayyil) reveal a dialect which is no longer considered "Proto-Arabic", but Pre-Classical Arabic. By the fourth century AD, the Arab kingdoms of the Lakhmids in southern Iraq, the Ghassanids in southern Syria the Kindite Kingdom emerged in Central Arabia. Their courts were responsible for some notable examples of pre-Islamic Arabic poetry, and for some of the few surviving pre-Islamic Arabic inscriptions in the Arabic alphabet

Answer 2

The Arabic language originated in the Arabian Peninsula and evolved from proto-Semitic languages. It was heavily influenced by the Qur'an, which standardized the language and spread its use throughout the Muslim world.
