"Tribute to Saadi is not only a tribute to elegant poetry and prose, but also a tribute to ethics, wisdom, and profound knowledge," the message reads.
"Undoubtedly, Saadi is one of the cornerstones of Persian literature and the product of poetry and prose, forming one of the most prominent elements of our contemporary culture," it adds.
In his statement, Ayatollah Khamenei praises the "straightforward and transparent" manner in which Saadi conveys his message to his audience.
"His straightforward and transparent way of speaking is another hallmark of this great popular and beloved teacher."
The Supreme Leader also calls on the commemoration congress to introduce the unknown aspects of Saadi's personality and the brilliance of his art, paving the way for Iran's revolutionary generation to benefit from "this valuable treasure."
"Literature and art have had an excellent position as a language for expressing the highest Islamic thoughts throughout the history of Islam, and they must continue to have this position today," Ayatollah Khamenei says.
Iranians mark Saadi Day on April 20. This year, a number of foreign dignitaries and Iranian officials gathered at Saadi's tomb in Shiraz to pay tribute to Iran's "Master of Speech".
