«فَأَمْطَرَتْ ... وَسَقَتْ ... وَعَضَّتْ»
She rained, watered, and bit.
All three are feminine singular perfect verbs referring to the same woman. The surprise is that their objects appear as pearls, rose and jujube rather than tears, cheek and lips.
Amṭarat portrays tears falling; saqat portrays the wetting of a cheek; ʿaḍḍat portrays pressing the lips with the teeth. The sequence turns a static description into a vivid succession of actions.
