وَجَبَهْنَاهُمْ بِطَعْنٍ كَمَا تَنْهَزُ فِي جُمَّةِ الطَّوِيِّ الدِّلَاءُ
Meaning: We checked them with spear-thrusts, as buckets move forcefully in the pooled water of a lined well.
Jabahnāhum expresses stern resistance or forcefully checking the enemy. Tanhazu involves moving or agitating, while jummat al-ṭawī denotes water collected in a well lined with masonry.
This time the water is not spilling out. Instead, buckets move within the water. That distinguishes the comparison from verse 52: both use water, but one is a sudden outflow and the other a repeated jostling motion.
