The civilizational unity of the Islamic world is the result of the coexistence and interaction of the cultures and languages in the Islamic countries. When the Arabic language, as the language of the Qur›an, the language of Islam, and the Prophet›s way of life, entered Iran, it was considered not as an ethnic language and the language of the Arab people, but as the language of Islamic civilization. Therefore, the Arabic language should not be regarded as an ethnic language and the specific language of the Arab people. The many services that Iranians have had in shaping and consolidating the rules of grammar, syntax, and rhetoric of the Arabic language is a good sign of this claim. The immigration of the great poet of the Abbasid era, Abu Tammām Habib bin Aows Ṭā›ī, to Iran and stayed in the lands of Khorasan, Fars, and Azerbaijan, who authored a valuable, reliable, and effective literary book such as «Divān al-Hamāsa» in the city of Hamadan, as well as the many Iranian commentators of this work, such as Khatīb Tabrīzī, Marzūqī Esfahānī, and other Iranian literary figures are another evidence to confirm the fact that only in the context of a civilizational unity, such valuable interactions and symbiosis between languages can be observed.This article is presented on the occasion of the publication of the book «Seh Chikame Vilai by Abu Tammām Ṭā’ī».
