eleventh century. The text written by Abi. In addition to the complete text, there is an abridged version of it titled Montakhab men Ahd-e Ardashir bin Babak available. In the Islamic era, Ardashir's Testament was famous and is mentioned in many history and literature books. Al-Masudi has remarked it and has quoted a phrase of its about the last millennium. It is also named in Mojmal al-tawarikh and Farsnameh and in the latter it is mentioned about Khosrow I that "he suggested the testaments of Ardashir, son of Papak, and applied his preaches that were in that testament." The same matter is mentioned by Al-Tabari and Al-Tha'alibi. Al-Jahiz has mentioned Ardashir's Testament along with Bozorgmehr's Quotes and mentions that the writers (Kottab) used it. Al-Mubarrad (died 286 Hijri) writes that Al-Ma'mun had ordered his son's mentor to teach him Al-Watheg bellah the book of God and read him Ardashir's Testament and force him to memorize Kelileh va Demneh.

The Persian translation of that book is written in the translation of Nahayat-ol Aarab called Tajarob-ol Omam and also in Ferdowsi's Shahnameh.
