al-Husayn is among the most knowledgeable scholars, as are these others. If he or anyone else reports the consensus of Muslim scholars that the celestial spheres are spherical, then whoever subsequently disputes this—whether a speculative theologian, a jurist, or anyone else—is disputing a matter on which consensus had already been reached. I know of no one who disputes this who has not also transmitted the consensus mentioned by Abū al-Husayn ibn al-Munādī. Although disagreement concerning the movement of the celestial spheres has been reported from some of the early generations, I know of no disagreement among them concerning their sphericity.
