«صُمٌّ بُكْمٌ عُمْيٌ»
Deaf, mute, blind.
In context, this expression strongly depicts a refusal or inability to receive guidance; it does not require that every person described has physically lost the stated faculties. The words are from Qurʾān 2:18.
With compressed simile-like or figurative descriptions, identifying the context and the intended characteristic is essential. A literal dictionary gloss alone does not explain why bodily disabilities are invoked to convey a moral or cognitive state. The passage illustrates the need for contextual rhetorical analysis, not unrestricted substitution of every literal sense.
