The statement and the statement is one of the greatest books of Al -Jahiz, and it follows the book of animal in terms of size and more on all its books. If the animal book addresses a scientific topic, then the book of statement and clarification focuses on addressing a literary topic. But Al -Jahiz in these two books, like all his books, tends a philosophical direction. It is not limited to the animal book on animal news, their characteristics and their nature, but rather addresses philosophical topics such as cumin and generation, jewels and symptoms, and the indivisible part, Magi, Al -Hurriyah etc. In the book of statement and showing, it is not satisfied with presenting literary teams such as speeches, messages, hadiths and poems, but rather tries to lay the foundations of the science of the statement and the philosophy of language.
