فَفَاضَتْ دُمُوعُ الْعَيْنِ مِنِّي صَبَابَةً
عَلَى النَّحْرِ حَتَّى بَلَّ دَمْعِي مِحْمَلِي
Then tears overflowed from my eyes out of intense longing, down onto my upper chest, until my tears soaked the strap by which my sword hung.
Ṣabābah refers to overpowering love and yearning. The tears follow directly after the fragrant memory: what is pleasant to recall is also painful because it has passed.
The fāʾ links this scene to what precedes it, while fāḍat portrays tears that surge and spill over rather than a single restrained tear.
