The two Qur'anic words, 'osr' and 'yosr', require a revision of transcripts and interpretations. Most interpreters, and commentators have received the equivalent of "ease and simplicity" for the matter of "yosr" and "hardness" for the matter of "osr." The most important form of error in accepting this concept in verses 5 and 6 of the Sura "Sharh", is the mismatch between the verses and the truth. On this basis, most commentators have used the term "maa" in these two verses as meaning later, and They are influenced by a syntactic rule and a poor narrative and believe that the message of verse 5 and 6 of this sura is that it is two easy with every difficulty. The present article seeks to retrieve the notion of "Osr" and "Yosr" , with the descriptive-analytic method. The retrieval of the concept of "Osr" (difficulty) and "Yosr" (development), and also the study of the correct meaning of the term "Maa", Expresses a concept that has been neglected by most commentators and that concept is the expression of a divine tradition in verse 5; and the consolation and calm of the Prophet on the sixth. Therefore, the reason for the repetition of the verses is not emphasis; but each of the two contains an independent message that has been analyzed in this paper.
