«أقلب فيه أجفاني كأني»
I turn my eyelids through the night as though…
«أعد بها على الدهر الذنوبا»
I were counting time's offenses with them.
The overt subject is the length of the night and sleeplessness: repeated eyelid movement conveys restlessness. Inside that image appears another purpose, a complaint against time, imagined as the counting of its offenses.
The single coherent image serves both aims, with the second embedded in the first.
