fa طرح عدالت در سیرالملوک و مقایسه‌ی آن با مبانی کلام ابوالحسن اشعری تخصصي تاریخ اسلام Islamic History پژوهشي Research <em>Khaje Nizam-al-mulk </em>in<em> Siyar-al-muluk </em>endeavors to strengthen the power of the governing system by preventing social oppression and tyranny through selecting an outlook of justice known as &ldquo;power circle&rdquo; or &ldquo;cycle of justice&rdquo;. In this research, efforts have been made to conduct an analytical comparative study between the renowned comprehension of justice in <em>Siyar-al-Muluk</em> and <em>kalaami</em> (scholastic theological) viewpoints of <em>Abul-Hassan Ash-ari</em> in this respect. Therefore, the attitudes of the two-mentioned scholars about justice, responsibility, and executive power of the medieval Islamic governors and the companions of the Prophet Mohammad (PBUH) will be compared.&nbsp; This research seeks to demonstrate that <em>Khaje Nizam-al-Mulk</em> as a prime minister had diverse views on justice as opposed to <em>Ash-ari</em>. This hypothesis is based on the fact that basically the discourse of justice outlined in the two books of <em>Siyar-al-muluk</em> and <em>theological basis</em> of <em>Ash-ari</em> are not from the same essence, and thus may not be easily harmonized for similar applications.<br> &nbsp; خواجه نظام‌الملک طوسی, سیرالملوک, چرخه‌ی عدالت, کلام ابوالحسن اشعری Khaje Nizam-al-Mulk, Tusi, Siyar-al-Muluk, Cycle of Justice, Abul-Hassan Ash-ari’s Kalaam (Scholastic Theology) 53 70 http://journal.pte.ac.ir/browse.php?a_code=A-10-2-121&slc_lang=fa&sid=1 Nayereh Dalir نیره دلیر dalirnh@yahoo.com 1003194753284600212 1003194753284600212 Yes
