Rhetoric of Interrogation in Saadi's Bustan

One of the arguments in rhetoric is to examine the use of interrogative sentences in secondary purposes. The main purpose of the interrogation is to obtain information; but up to 32 secondary purposes have been written for Interrogations in some rhetoric books. In this descriptive-analytical study, the secondary purposes of the interrogative sentences in Saadi's Bustan have been analyzed. The purpose of this research is to determine what concepts Saadi has intended to present through rhetorical questions. The fundamental question in this research is to identify, to what extent did Saadi use the interrogative sentence in presenting his themes and concepts? The research is based on the assumption that due to Saadi's mastery in rhetoric criteria of language, he has taken great advantage of the secondary capacities of the interrogative sentences, especially in conveying themes of reproach and denial. In Saadi's Bustan, in total, 379 cases of rhetorical interrogations have been used. Out of which, in 289 cases, the poet used one type of interrogative tools to ask questions, which included a variety of 19 questions. Of these 19 cases, only the Arabic word "kaifa" serves as a question mark. The word "Che" has been used 129 times, accounting for about 47% of all query words in Bustan. In many cases of rhetorical questions, he begins the interrogations by the word "no". The poet's intention in this way of expression is to draw the reader's attention and emphasis on the theme. In total, 379 cases of rhetorical interrogation have been utilized in the Saadi's Bustan. These questions have raised 32 different themes. What is important in terms of the style and understanding of the poet's thinking is that in 241 of these questions, directly or indirectly, ethical themes are presented.
