ولا بالكيفية من اللون والطعم والرائحة
Nor with bodily qualities such as color, taste and smell.
In this context kayfiyyah covers sensory and bodily qualities such as color, taste, smell, warmth, coldness, moisture and dryness. Saying an object is red or warm describes a physical condition.
Attributing such creaturely conditions to the divine essence would place God among material subjects whose features vary as bodily accidents.
The denial of physical modality does not make divine attributes meaningless. Knowledge and power are affirmed; what is denied is treating them—or the divine essence—as a material condition comparable to color, taste, temperature or composition.
