Arabic Literature

Abstract Undoubtedly the founder of any knowledge is who laid the cornerstone of that. On the base of many narratives, Imam Ali (AS) is the founder of Arabic grammar who directed Abul Asvad Addoali to expand Arabic grammar. But some of modern scholars imitated some orientalists and on the base of a few narratives denied that the founder of Arabic grammar is Imam Ali (AS). They also refused to accept the ability of the early Arabs and Muslims to establish a science. Through responding to these deniers, this paper shows weaknesses of their opinions. The authors of this paper have also showed that the Arabic grammar has not been influenced by other languages.
