Face covering as a mark of status
In pre-Islamic Arabia a covered face marked a free woman; enslaved women went uncovered. In war, free women uncovered deliberately, to be mistaken for slaves and escape capture. Three poems record it.
Before Islam, dress in Arabia carried social information. Many free women covered the head and body, and some covered the face. Enslaved women wore neither head covering nor niqab. The difference was legible at a glance.
What happened in war
Because their status made them valuable, free women were the prime targets for capture. Some responded by uncovering — head and face — so as to pass for slaves.
وَنِسْوَتُكُمْ فِي الرَّوْعِ بَادٍ وُجُوهُهَا ... يُخَلْنَ إمَاءً وَالإِمَاءُ حَرَائِرُ
And your women in the terror of battle, their faces bared — they are taken for slaves, though the slaves are the free ones.
Al-Marzūqī (d. 421 H), commenting on this poem, explains that free women disguised themselves as slaves for fear of capture, going out exposed and setting aside their own sense of modesty, because the object of taking such women was humiliation rather than ransom or property.
Two further poems describe the same situation. ʿAmr b. Maʿdīkarib, a mukhaḍram poet, writes of Lamīs — a woman of great beauty forced into the open by war, where what was exposed must at minimum have included the face, since the whole point of the description is that her hidden beauty became visible. Muhalhil b. Rabīʿah gives a third instance.
The pattern recurs across many jāhilī poems; these are examples rather than the whole record.
Why this matters beyond history
This is not a curiosity. It is load-bearing for the central scriptural argument (see the jilbāb verse), which turns on the phrase "so that they may be recognised": recognised, on this reading, as free women rather than slaves. Without the social fact, that reading has nothing to stand on.
A necessary note
The free-woman / enslaved-woman distinction runs through this material and cannot be removed without removing the argument. It belongs to the social order of the time, which the sources describe rather than commend, and it is recorded here because the evidence is unintelligible without it.

According to this note, why did some free women in pre-Islamic Arabia deliberately uncover their faces during war?
