وَمَا مَنَعَ الظَّعَائِنَ مِثْلُ ضَرْبٍ تَرَى مِنْهُ السَّوَاعِدَ كَالْقُلِينَا
For the protection of these women, the poet imagines a fierce clash in which forearms are scattered like small pieces flung through the air.
Mā ... mithlu emphasizes a strong negative comparison: in the poet’s claim, no defence equals violent resistance. Al-sawāʿid is the plural of sāʿid, forearm.
The comparison ka-l-qulīnā portrays small objects flying away, heightening the violence of the image. This is an instance of extreme martial hyperbole in early Arabic poetry, not an endorsement of violence.
