Free women were captured but not enslaved; they were offered for marriage and were not sold like other slaves. After losing their men in the battles, their ladies used to marry the gentlemen of their enemies. This was a custom. The Quran mentions free women captives and slave girls separately. وَالْمُحْصَنَاتُ مِنَ النِّسَاءِ إِلَّا مَا مَلَكَتْ أَيْمَانُكُمْ 4: 24 مَّا مَلَكَتْ أَيْمَانُكُم مِّن فَتَيَاتِكُمُ الْمُؤْمِنَاتِ 4: 25 The narrators sometimes do not differentiate between them, but the treatment they receive made the difference clear.
