Disputes between classical Muslim theologians are often spoken of in very abstract terms. What is often forgotten, however, is the human  relationship that would have existed between such theologians. Through the example of the Shīʿī Hishām b. al-Ḥakam and the Ibāḍī ʿAbdallāh b. Yazīd al-Fazārī, I demonstrate how two theologians with striking doctrinal differences nevertheless maintained a very strong friendship,  as evidenced by the mention of this friendship in various genres of literature. Such a friendship serves as a prompt to rethink our assumptions about how classical Muslim theologians interacted with each other and as a precedent on which to base intra-Muslim interactions today.
