Analyzing the choice of words in the Qur'an in the blessed Surah "Luqman" with the approach of "the purpose of the Surah" in the discourse of tadabbor

Contemplation and interpretation of the Holy Quran is based on the meanings of the words. Examining the meanings of the words is considered the most fundamental stage of contemplation and interpretation. Therefore, understanding the meanings of the words has a fundamental place in contemplation and interpretation of the Qur'an. Quranic terms have different layers of meanings. These semantic layers are used for the purpose of semantic development. A comprehensive and detailed examination of these terms helps us to discover these layers. In order to carefully investigate these terms, it is necessary to search for the lexical and literal meanings and their semantic components. In order to discover the literal and lexical meanings and semantic components of Quranic terms and words, it is necessary to examine the purpose of each Surah. In this research, using the descriptive-analytical method, the purpose of Surah Luqman (Arabic: لقمان) is first examined, and then some important words of this Surah are interpreted in the light of its purpose. The literal meanings of the three words Verses (Arabic: آیات), Book (Arabic: الکتاب) and wisdom (Arabic: الحکیم) in Surah Luqman was investigated. In this surah, the Verses refers to the important training principle of sign study (Persian: آیه بینی), the Book emphasizes the important training principle of Source of training and wisdom seeks to express the purposefulness of training and the reliability of the source of training.
