كَقَوْلِهِ: لَدَيَّ أَسَدٌ
As in saying, “I have a lion.”
When the context indicates a human, the target is an actually perceivable individual. The source concept is the wild lion, and the intended target is a brave person. Courage is the common feature that warrants the transferred expression.
Three elements should be kept distinct:
Mustaʿār minhu — the lion as source.
Mustaʿār lahu — the brave human as target.
Qarīnah — evidence excluding the literal animal.
The effect is stronger than merely saying “brave”: the lion-image is deployed to intensify the description.
