تُمْسِي وَتُصْبِحُ فَوْقَ ظَهْرِ حَشِيَّةٍ وَأَبِيتُ فَوْقَ سَرَاةِ أَدْهَمَ مُلْجَمِ
She spends her evenings and mornings upon a soft bedding, while I spend the night upon the back of a bridled black horse.
Tumsī wa-tuṣbiḥu extends over evening and morning, whereas abītu places the poet through the night. Her bedding signals ease, whereas adham muljam is a black, bridled horse.
The parallel structure creates a contrast of circumstances. The poet shows the hardship of travel through two sharply opposed scenes rather than by announcing that he suffers.
