Whoever believes that a human being is divine, that there was a prophet after Muhammad—may Allah bless him and grant him peace—or that he was not a prophet but that Alī was the prophet instead of him and Gabriel simply erred: these and similar doctrines plainly reveal the unbelief of those who hold them to anyone with even the slightest knowledge of Islam.
This is unlike the Khawārij who declare Alī an unbeliever and curse him, and unlike those(2) among the followers of Muāwiya, the Banū Marwān, and others who fought and cursed him. They professed Islam and its laws: they established prayer, gave zakāt, fasted Ramadan, performed pilgrimage to the Ancient House, and regarded as forbidden whatever Allah and His Messenger had forbidden. No manifest unbelief was found among them; rather, the rites and laws of Islam were manifest among them and held in reverence by them. This is known to everyone acquainted with the history of Islam. How, then, can it be claimed that all his opponents declared him above reproach, unlike the three caliphs?
Indeed, if those who hated him and were loyal to Uthmān are compared with those who hated Uthmān and loved Alī, the former will be found better(3) than the latter in several respects. Those who declare Uthmān above reproach while criticizing Alī are greater and more religious
