Poetry as the everlasting art is prevalent in all times and in all nations. As an innate instinct, and thanks to the Holy Qur'an and Islam, as well as the pure teachings of Imam, poetry became eternal. In the present study, to trace the desirable poetry from the viewpoint of Imam Sadiqconsidering the events of the time, an example of his poems and hisprominent followers’ was investigated. Regarding the challenges of enemies and creating cults, Imam explained the status of Imamate and mentioned its necessity. Therefore, the beauty of poetry was distinguished due to ethics and good characters. Finally, in Imam's poetry and some of his prominent disciples’, values such as faith in God, belief in prophecy, Imamate and life after death, are the most important ones which are highlighted. The poets, who were influenced by Thaqalayn and especially qualified to benefit from the words of Imam Sadiq (PBUH), reflected the injustice and oppression to the Holy Inmate (PBUT) which were particularly outlined in the movement of Imam Hossein. With Imam’s encouragement, pure Islamic thoughts, mostly in Shiitepoetry, obtained everlasting worth. Thus, for composing loyal poems, the poets could gain the honor to be praised by Imam.
