Muʿjam al-Aḥādīth al-Muʿtabara, Prohibition on Debate and Argumentation – Ḥadīth #8
[8/-] Rijal al-Kashshi: Hamduwayh from Ibn Yazid from Ibn Abi Umayr from Muhammad b. Hukaym who said: the names of those who engaged in Kalam (speculative theology) were mentioned to Abi al-Hasan عليه السلام – so he said: as for Ibn Hukaym then leave him be. Comments
The `Aimma took a negative stance to Kalam acc. to some. Of course there is nuance to this and what they were against was a rationality that was unleashed without any checks viz. revelation. Some of the most prominent companions of the `Aimma were recognized theologians although they attracted controversy and drew censure from other wings of the Imamiyya who were strict traditionalists.
