وَأَرْوَعُ نَبَّاضٌ أَحَذُّ مُلَمْلَمٌ
كَمِرْدَاةِ صَخْرٍ فِي صَفِيحٍ مُصَمَّدِ
Her heart is keenly responsive, quick to pulse, compact and strong—like a hard stone implement held firmly within a reinforced slab of rock.
The implied object described in this verse is the animal’s heart. Arwaʿ suggests being startled easily, nabbāḍ a lively beat, aḥadhdh quickness, and mulammam compact solidity.
Mirdāt ṣakhr evokes a hard stone tool used for breaking rock; ṣafīḥ muṣammad is a firmly set stone surface. The passage is a powerful literary figure for alertness and strength, not an anatomical description of how a camel’s heart mechanically operates.
