ثم منه أي من المجاز ما يبنى على التشبيه
Then among figurative expressions are those built upon simile.
Some transfers from a lexical sense to a related intended sense rely on a resemblance between two things. To understand these transfers, one must first understand what the resemblance consists in and how a comparison operates.
“Zayd is brave like a lion” explicitly states a comparison. “Zayd is a lion,” when figuratively said of his courage, can become the basis of istiʿārah (metaphor). The two forms should not be collapsed: one states the similarity openly, while the other transfers an expression figuratively.
