The poets of the Yassavi school have a special place in the history of Uzbek literature, manuscript sources testify to this. Sulayman Bakirgani is the most powerful poet of this school. Alisher Navoi mentions Ahmed Yassavi in "Nasaimul-Muhabbat" and mentions him as "Shaykh ul-Mashayikh", "Qiblai prayer of the people of Turkestan". While giving information about his follower Sulayman Bakirgani, he cites an excerpt from his poem, stressing that "Hakim was the language of wisdom" and that his wisdom was popular among Turks.
