Ismail is also known for his poetry using the pen-name "Khaṭā'ī" ( "Sinner"). He wrote in the Azerbaijani language, a Turkic language mutually intelligible with Turkish, and in the Persian language. He is considered an important figure in the literary history of Azerbaijani language and has left approximately 1400 verses in this language, which he chose to use for political reasons. Approximately 50 verses of his Persian poetry have also survived. According to Encyclopædia Iranica, "Ismail was a skillful poet who used prevalent themes and images in lyric and didactic-religious poetry with ease and some degree of originality". He was also deeply influenced by the Persian literary tradition of Iran, particularly by the "Shahnameh" of Ferdowsi, which probably explains the fact that he named all of his sons after "Shahnameh"-characters. Dickson and Welch suggest that Ismail's "Shāhnāmaye Shāhī" was intended as a present to his young son Tahmasp. After defeating Muhammad Shaybani's Uzbeks, Ismail asked Hatefi, a famous poet from Jam (Khorasan), to write a Shahnameh-like epic about his victories and his newly established dynasty. Although the epic was left unfinished, it was an example of "mathnawis" in the heroic style of the Shahnameh written later on for the Safavid kings.
