Investigating the Concepts of the Words “’Usr” and “Yusr” in Qur’an based on Dual (Contrastive) Logical Approach

The element of dual contrastive is a fundamental topic in linguistics that helps structuralists and post-structuralists in the studies of contemporary literary criticism for analysis of the meaning of two opposites. The two words “’Usr” and “Yusr” are the choices for analysis and contrastive investigation in this research based on the verses in which the two words are in the vicinity of each other. This research, that has investigated the concepts of these words based on dual contrastive relation using the descriptive-analytical method and sometimes the interpretive method, implies that God has taken advantage of dual contrastive in order to explain many of the religious concepts, and in doing so He has made the concepts easier to understand and to accept for the audience while making them clear. Application of the aforementioned words is mostly used in the concept of problems being solved and promising hope. These two words are among the promising words of God the Almighty that calms human and gives hope for pride and happiness.
