Fatīt means small fragments or particles, while al-misk is the aromatic substance musk. Fatīt al-misk is an iḍāfah: the first noun is in construct with the second. The aroma is thus represented through a concrete, scattered material rather than as an entirely invisible quality.
Naʾūm follows the intensive pattern faʿūl, suggesting habitual or abundant sleep; al-ḍuḥā identifies the forenoon. The phrase indicates a recurring condition of late morning rest, not merely one incident of waking late.
The opening tuḍḥī also places the scene in the hours of daylight. Time, bedding, fragrance, and lifestyle are integrated, making this more than another description of physical appearance.
