«غُدَافِيَّةِ الْإِهَابِ»
With a covering as black as a raven's plumage.
Ghudāf is associated with a dark bird; ihāb means hide or outer covering. The night is imagined as a body clothed in a dark skin.
The earlier phrase gave night youth; this one gives it a covering and colour. Together they form a vivid personified landscape, carrying more sensory force than a plain statement that it was dark.
