However, this depiction of using the createdness of Qur'an as a litmus test for Mu’tazilism or Shi’ism can be misleading. While there is an overlap between the two schools of thought on this question, Mu’tazilism and Shi’ism were not the only theological currents to subscribe to this belief, therefore there may not necessarily be a link between the two in the event of al-Ma’mun's Mihna. Furthermore, it is inconclusive whether Shi’ism during this period had fully embraced the notion of the createdness of the Qur'an, or whether it is a retrojection from later times after Sunni and Shi’ism had developed its doctrines. While some scholars argue that the prevailing view among Shi’ite theologians at this time followed the teachings of Ja’far as-Sadiq, who believed in its uncreatedness, other sources challenge whether Imam Ja’far as-Sadiq held such a view.
