قَبْلَ مَا الْيَوْمِ بَيَّضَتْ بِعُيُونِ النَّاسِ فِيهَا تَغَيُّظٌ وَإِبَاءُ
Meaning: Long before today, our standing had made our opponents’ eyes turn white with anger and envy; the image conveys their rage and our refusal to yield.
Bayyaḍat bi-ʿuyūn al-nās is not a clinical report of blindness; it is heightened imagery for opponents consumed by resentment. Taghayyuẓ suggests fierce anger, and ibāʾ proud refusal to submit.
The imagery simultaneously portrays the adversary’s response and the speaker’s sense of tribal dignity.
