Mind and Language in Abu Yaqub Sejestanis Communication Theory

Muslim Mutakallimun can be considered pioneer linguists in the east due to their attention to language. Since they were focused on studying different aspects of the linguistic I’jaz of holy Qoran and because of their contemplation in the themes related to the word of
God like Hoduth and Qidam, they have discussed studied delicate linguistic topics like descriptions, functions, semasiology and hermeneutics. Abu Yaqube Sejestani is an Iranian Muslim Mutakallim in 4th century (Hijri). He paid serious attention to mind and language as a system in "Kashf ol Mahjoob", and introduced a communication theory based on the “system of speech and language” including three dimensions named "Qasd", "Tab’?" and "Orf".Sejestani believes these elements are meaningful and significant when they are all together, therefore any deficit in these elements, omission or ignoring even one element will result in a disconnection between speech and the speaker, and therefore, breaking the speech chain and failure in communication. The advantage of his theory of communication is that he addressed hermeneutics, especially in holy texts. By introducing and analyzing “Sejestani’s system of mind and language, and
communication theory” in this paper a clear description of his priceless ideas is presented.
