that this long night of separation has no dawn coming after it.
Explanation: The 'long night of separation' is a classic Persian image for the suffering of the parted lover, made worse here by the sense that morning, and relief, will never arrive.

تو که خفتهای به راحت دل تو خبر ندارد
که شب دراز هجران ز قفا سحر ندارد
