The life, creativity and the literary heritage of the genius Azerbaijani poet and thinker Ni-zami Ganjavi are studied with great interest in many countries of the world, including Arabic East. The first and the most notable monograph dedicated to life and creative activity of the great poet was created by Egyptian scientist Abd al-Nayim Muhammed Hasanain (Egypt, 1954, 527 pages). In the first part of this study, consisting of two books, was examined the Nizami’s epoch and such ruling dynasties as Great Seljukids, the Seljukids of Iraq and Asia Minor, the rulers of Shirvan and Maraga, the Abbasids of Iraq, the Ismailits of Iran, the Sunni and Shiite religious sects and socio-economic situation of Nizami era. The author of the book, referring to the re-marks and notes contained in the poems of Nizami, believes that the poet was born in 1144 and died in 1211/12. The second part of the monograph was devoted to the poetry of Nizami. After detailed analysis of the most famous poems ofNizami, the author stated that the poet wrote his first poem "Treasury of mysteries" under the influence of the poem "Hadikatul-hakaik" by the popular Persian poet Sanai. However Nizami’s style is more gracefull. Comparing the poem "Khosrov and Shirin" by Nizami with the poem of the same name in "Shah-name" by Firdowsi, Hasanain comes to the conclusion that it was Nizami who first elaborated the poem in a completely new aspect. The poem by Nizami differs from the same by Firdowsi by its plot, sequence of events, landscape images and etc. The author came to the conclusion that Nizami was the first poet who created the love story of Khosrov and Shirin in the form of a romantic poem. The image of Iskender (Alexander the Great) created by Nizami also differed in interpretation. If Firdowsi created the image of Iskender as a patron-hero, Nizami portrays him as a just ruler and a wise philosopher.Hasanain points out that Nizami elaborated the stories of "Shahnameh" by Firdowsi not by repeating and imitating his great predecessor, but in creative way, what opened the new possibilities for the poets of new generation. By this Hasanain rejected the opinion of Iranian scholars (Rezezade Shafak, Zabihullah Safa) that Nizami was a direct imitator of Firdowsi. According to the author, Nizami was not a poet – an epigone, but an original artist who inno-vatively enriched Persian literature in form and content. Thanks to this, the poet created his own literary school, becoming the founder of one of the most influential literary schools in the East. It can be said without exaggeration that poetry by Nizami served as a model for representatives of Persian language poetry who created poems in mesnevi genre which was one of the most popular genres of oriental literature. Despite some shortcomings (the author gave more space to retelling the content of Nizami’s poems than to their ideological and artistic analysis and he was little familiar with the studies of Soviet nizamiologists), the monograph of the Egyptian scientist Abdal-Naim Muhammad Hasanain was very valuable research devoted the life and cretivity of Nizami, as well as the socio-political and economic life of Azerbaijan in XII century.
