The source includes a poem that depicts wine through celestial imagery. It uses the metaphors “laha al-badru kaʾs” (“the moon is its cup”) and “wa-hiya shams” (“it is a sun”), also bringing a crescent into the scene.
“The moon is its cup” is a metaphorical substitution.
“It is a sun” attributes solar brilliance as an imaginative quality.
Neither literal identity is asserted. The poet combines celestial images into a striking scene, illustrating poetic influence rather than evidential demonstration. The passage is analyzed as literature, not as a recommendation to drink.
