Can it be true in literature that some accomplished poets get overshadowed and misunderstood by the impressive contributions of several of their contemporary poets based on a distinction in attitude and expression, using normative or a specific non-normative language, and that this problem has prevented research by others? Of course this problem might not have been the result of the prowess of a few; the scarcity, understanding and discrepancies of manuscripts, also might have caused a famous scholar to be forgotten. Even though Zia ad-Din Khojandi, according to Zabihollah Safa, was one of the literary masters of the end of the twelfth century, and his firm expression was proof of his poetic skills, like other unfortunate contemporaries, he has remained unknown. How has a poet who has shown his skills in a variety of poetic forms (fragment, quatrain, sonnet, and, especially, ode); and whose poetry contains many examples of eulogy, elegy, satire, raillery, love, nature, etc; and also one who has recounted the history of the accession and dismissal and death of many important personages, who have been neglected by history, remained so unknown. The writers of this brief, after a close study of his seventhousand-line book of verse, have reach a bright horizon as to the social, scientific and religious life, and also the approach to the composition of poetry that has remained hidden to literature until now. In this article concise and logical issues relating to the life, history and knowledge of the poet have been studied.
