بَاكَرْتُ حَاجَتَهَا الدَّجَاجَ بِسُحْرَةٍ لِأَعَلَّ مِنْهَا حِينَ هَبَّ نِيَامُهَا
I set about satisfying that desire very early at dawn, before the cock’s call, so that I could drink again when the sleepers awoke.
Bākartu describes going or acting very early. Al-dajāj refers to fowl or cocks, and suḥrah to the late part of the night before dawn. Li-aʿalla expresses purpose; ḥīna habba niyāmuhā locates the later moment when sleepers awaken.
