There is no doubt that the Samanids sought to revive ancient Iranian culture. Their support and encouragement of the poet, Abu Mansoor Daqiqi to compose Khwadāy-Nāmag should be considered for this reason. But Daqiqi was not the only poet whom the Samanis had assigned to such a great work. Rudaki, the greatest poet of the Samanian court, also had a mission to compose Kalīla wa-Dimna into poetry. So far, a lot has been said about the reason why Khwadāy-Nāmag was written into poetry, but not much attention has been paid to why Rudki was chosen to compose Kalīla wa-Dimna into poetry. In this article, we have tried to investigate the reason for the choice of Kalīla wa-Dimna by the Samanids and its poetry by Rudaki.What is certain is that due to the Indian origin of Kalīla wa-Dimna, it cannot be considered as a work written in Iranian culture, but the point that should be paid attention to is the changes (intrusions and possessions) that Iranians such as Ibn al-Muqaffa made in this text. In this way, they have given it an Iranian color; the changes that have made Kalīla wa-Dimna a work that teaches the "art of life" and the wise way of life (of course, in harmony with Iranian culture). The analysis of the stories of Kalīla wa-Dimna, and especially stories like the story of the lion and the cow, and pious and his guest, prove this claim well. In brief, the intention of the Samanids in appointing Rudaki to compose Kalīla wa-Dimna was to revive the wise way of life of the ancient Iranians and to promote it. If this statement is true, then a mission for Iran should also be given to Rudaki and his name should be placed next to poets such as Daqiqi and Ferdowsi, who played a great role in the revival of ancient Iranian culture.

Introduction
The power of Arabs over the Iranians and their domination over Iran did not last more than two centuries, and the Iranians soon began to think about reviving their former culture. These efforts can be examined in two periods. In the first period, some began to translate the works of their ancestors into Arabic. The second period is when, not individuals, but the Iranian rulers, became the pioneers in reviving the culture, language, and thought of their ancestors. For their complete independence from the Islamic Caliphate, the Samanids not only supported the Persian language, like the Saffarids, but they also commissioned poets to put some works into poetry. The most well-known of these works is the Khwadāy-Nāmag. Daghighi’s encouragement to compose the Khwadāy-Nāmag into poetry had a political dimension and was intended to revive the history of ancient Iran. However, of note is that it was not only Daghighi whom the Samanids commissioned to do a great task. He was not even the first poet chosen by the Samanids to fulfill a great task, since before him, Rudaki - who was the greatest poet of the Samanid court - had also been commissioned to conduct a similar great task. The current study examines the Samanids' motivation in persuading Rudaki to compose Kalīla wa-Dimna into poetry.

Materials and Method
This research follows a descriptive-analytical approach and relies on library studies to examine and analyze the Samanids' motivation in persuading Rudaki to compose Kalīla wa-Dimna into poetry. To achieve this purpose, an attempt has been made to utilize metatextual knowledge, especially motivations related to the Iranian culture, in explaining the subject.

Discussion & result
Apart from the detailed classifications, one of the most important findings of this research is that the main core of composing Kalīla wa-Dimna into poetry and the role of the Samanids in this endeavor, is a type of Iranian-culture discourse that the Samanid kings attempted to establish and institutionalize in line with the trends of their time and in opposition to the Arab Muslims. They had considered the Persian language to have an important and fundamental role, and for this reason they did their utmost to encourage and motivate poets to achieve the mission of highlighting the Iranian culture.

Conclusion
Based on the data of this research, the following can be claimed. The main goal of the Samanids in appointing Rudaki and encouraging him to compose Kalīla wa-Dimna was to consolidate the Iranian culture. The revival and promotion of the wise lifestyle of ancient Iran was only possible through language. Poets of the past were the eloquent speakers of their time and played a great role in promoting, establishing, or marginalizing and eliminating specific discourses. Therefore, the rulers attempted, in various ways, to use them to achieve their goals. Of note is that the Samanids' pro-Iranian spirit and the symbolic confrontation they had with the Arab Muslims can be considered the initial and hidden motivations of this thought and idea.
