ascetics concerning their spiritual masters—that they are divinely protected—and even less tenable than the belief of many of the early (1) Syrians [the followers of Banū Umayyah]: (2) that the imām must be obeyed in all things, and that when Allah appoints an imām, He accepts his good deeds and pardons his misdeeds. For those who go to extremes regarding spiritual masters, even when they go to extremes over a particular master, do not restrict guidance to him, forbid people from following anyone else, [or declare anyone who does not acknowledge him as a spiritual master to be an unbeliever] (3). Nor do they claim for him the degree of infallibility that these people claim—except, of course, for one who has departed (4) from the religion altogether. Such a person belongs among the extremists regarding spiritual masters, such as the Nusayriyyah, the Ismāīliyyah, and the Rāfidah.
In any event, the evil among them is greater [than among others] (5), their extremism is more severe, and the evil found among others is but a part of theirs.
As for the extremists among the Syrians [the followers of Banū Umayyah] (6), they would say (7): [When Allah appoints a caliph, He accepts his good deeds and pardons his misdeeds. They would sometimes even say that He would not call him to account (8).
