صُمٌّ بُكْمٌ عُمْيٌ
Deaf, mute, blind.
These words occur in Sūrat al-Baqarah (2:18) in a portrayal of people's spiritual condition. They are not necessarily asserting a literal, total loss of bodily faculties; rather, they vividly represent a failure to hear, express, and see the truth.
This formulation appears in the discussion of emphatic simile because the descriptions are attributed with extraordinary intensity, as though the persons had become those conditions themselves. Its comparison-based force remains relevant even without an expressed particle such as “like.”
The object is to understand the rhetorical force, not to make an unsupported physiological claim about the people described.
