Historian David R. W. Bryer defines the Druzes as ghulat of Isma'ilism, since they exaggerated the cult of the caliph al-Hakim bi-Amr Allah and considered him divine; he also defines the Druzes as a religion that deviated from Islam. He also added that as a result of this deviation, the Druze faith "seems as different from Islam as Islam is from Christianity or Christianity is from Judaism".
