Reading: Ghulats

According to Dr. Farhad Daftary (Ismaili historian) in his book (page 63)

Ghaliya or ghulat (singular, ghalı, exaggerator). This was a general term of disapproval, probably coined by some early Shıı authors and adopted by the heresiographers, in reference to those Shıi accused of exaggeration (ghuluww) in religion and in respect to the imams and other Shıı personalities.

The criteria of ghuluww were determined by the Shııs themselves, since the Sunnıs remained basically uninterested in the divergences within Shiism.
