This line of poetry uses vivid imagery to convey a sense of beauty and richness. 'The spread is like musk' suggests a pervasive and pleasant fragrance, likening it to musk, which is a symbol of luxury and allure. 'The faces are like dinars' implies that the faces are bright and valuable, akin to gold coins. 'And the fingertips are darkened' could suggest a contrast, perhaps indicating the toil or effort behind the beauty, or it could be a reference to the use of henna, a traditional adornment. This use of metaphor and simile is typical of classical Arabic poetry, which often celebrates beauty and elegance through such comparisons.
