Medieval Christian writers saw a real philosophical-religious rift within Islam.

Evidence

There was a corollary, put forward by a few well-informed writers, that there was an acute quarrel between philosophy and religion within Islam itself. Mark of Toledo seemed to take this for granted, when he said of ibn Tiimart, cum in nullam crediderit legem, utpote philosophus Algazelis didasculus. Vitry took it for granted that educated Muslims followed Muhammad’s example but derided his doctrines. William of Auvergne was shocked that so great a philospher as ibn Sina should expressly admit corporal delights in Paradise which the Qur’an had promised. — Norman Daniel, Islam and the West, 370
