The research was directed to the modern critical books that received the book “Al-Muazana bayna Abu Tammam and Al-Buhturi” by Abu Al-Qasim Al-Hassan bin Bishr for Al-Amidi (370 Ah) to answer the main question: what are the main features of criticism in Al-Muazana book in contemporary criticism books? The study aims to reveal the views on the critical approach of Al-Amidi, and then trying to reconcile the opinions of contemporary critics that discussed the method of Al-Amidi in his book, one of them was the first book in which applied criticism appeared. One of contemporary critics’ opinion was that it was characterized by investigating the opinions of the old critics about the Poetry of the Poets, a book in which objectivity was achieved in equalizing and neutrality. Contemporary critics almost agreed that Al-Amidi was characterized by planning his approach in the introduction to his book and its application. The most important results: Al-Amidi explained the poetic thefts attributed to Al-Buhturi and Abu Tammam simultaneously. He explained the many poetries that Abu Tammam took from others with his many archives. Contemporary critics pointed out that Al-Amidi was not interested in the linguistic errors of poets, and he argued that there were many mistakes of ancient poets. Contemporary critics differed about Al-Amidi’s intolerance of the poet Al-Buhturi and all his arguments.
