Persian prophet and writing works in Arabic

One of the main characteristics of all the divine messengers is speaking with the language of people to whom have been sent. It is obvious that the most familiar persons to a prophet or divine leader are people of his tribe, city, and nation. Therefore, a prophet or divine leader needs to speak with people of his nation and city in a generally known language to achieve a correct and logical communication with them.
