The use of letters emphasis in Arabic is one of the phenomena by which Arabic is recognized and has taken large amount of grammarians and rhetoricians discussion. Our research entitled The Effect of Using () in Emphasizing the Quranic Meaning shows the effect of emphasis in the Koranic textual semantic. Emphasis by using letters in Arabic is divided into two parts: The first is the repetition of the same letter in the sentence, and this is called lingual emphasis. The second is certain letters are used to mean emphasis in particular, e.g. superfluous prepositions ( ) that abolish and the emphatic two ()s. We have presented at the brgining of our research a grammatical presentation in which we identified what grammarians had said about the emphatic () for present verb. Then we analyzed the Koranic verses that contained emphasized present verb. That Koranic use has three modes. First, the result clause of an oath, which is the most mentioned and most frequent in Koranic expression, Second, The emphasis of subjunctive clause with () and (), which is mentioned in Qoran in nineteen places, and third, the emphasis of non-assertive clauses, and inhibition was preferred to other types of non-assertive styles that are emphasized, also non-assertive clauses with inhibition () of with interrogative (). We aimed to choose Koranic texts to enforce our analysis.
