How Accurate is the Ascription of Khan al-Ekhwan to Naser Khosrow Qubadiani?

Naser Khosrow is one of the famous Iranian poets and writers who lived in 11th century. There are some works by Naser Khosrow in prose or verse, all of which have been written to promote Ismailia teachings and beliefs. Due to the fact that many works have been mistakenly ascribed to Naser Khosrow over the years, there are doubts about the accurateness of the attribution of some of his major works in the last 100 years. One of the mentioned works is Khan al-Ekhwan, containing one-hundred sections (queues) various viewpoints about Ismailia. Through two methods of: a) Explaining Naser Khosrow's scientific method in creating his works; and, b) comparing Khan al-Ekhwan with his other prose works, and utilizing three techniques of: 1. Text mining to overview the text similarity metrics through bag-of-words and cosine models; 2. Reviewing the stylistic and lingual features of Khan al-Ekhwan; and 3. Studying Khan al-Ekhwan's structure, it has been proven, in present study, that although a significant part of Khan al-Ekhwan (thirty-eight queues of one hundred) is the translation of Yenābi' by Abu Yaqub al-Sijistani, and in fact the contents of these sections belong to AbuYaqub al-Sijistani, but it can be claimed that these writings are from Naser Khosrow's pen, considering the stylistic and lingual signs of  the work.
