كما في تشبيه فحم فيه جمر موقد ببحر من المسك موجه الذهب لإبرازه
As in comparing coal with glowing embers to a sea of musk whose waves are gold, so as to make its image striking.
The image sets a dark background against bright glowing elements, converting a perceivable arrangement of coal and fire into an extraordinary imagined seascape. The comparison term—a sea of musk with golden waves—is not an everyday observed object.
The purpose is not to claim that the coal literally has musk's fragrance or that fire is a sea. Rather, the combined visual configuration of darkness and brilliance becomes remarkable through a novel counterpart. This is a clear route by which a simile serves the purpose of making an image unusual.
