The principles of knowing of addressee in Nahj al-Balagha according to Imam Ali's viewpoint

Human relationship is foundation stone of human societies. Every communication includes at least three components: the speaker (the sender of message) message (speech- text) and the audience (the receiver of the message). Therefore, the purpose of communication is to convey a message. In order to give the audience a message in the best way, each speaker requires the information regarding the audience that according to that information, offer the content of message into reasonable and effective structure. Nahj al-Balagha consists of series of religious message that is aimed at people with different characteristics.
