Semantic evolution and social function of the word confidence in the literary culture of the Qur'an

Semantics, which has become common in Quranic studies in recent years, has been remarkably effective in recognizing the concept of Quranic words in various methods based on the text itself. Examining the semantic components of words in text is one of the methods that can discover new and hidden dimensions of the words to the researcher. Synonyms and antonyms and semantic components of "iṭmīnān" are among those that are studied and extracted in the present article. In this study, first, the meaning of "iṭmīnān" in pre-Islamic Arabic culture is investigated, then its semantic components in the Qur'an are examined which led to the recognition of the meaning of this word. The result of the research demonstrates that due to the harshness of Arabs, the original meaning of "iṭmīnān" is more apparent relief and tranquility, but based on its relation with words such as faith, it is semantically developed in the sense of peace of heart which highly plays a role in human spiritual education.
