ثُمَّ مِلْنَا عَلَى تَمِيمٍ فَأَحْرَمْنَا وَفِينَا بَنَاتُ قَوْمٍ إِمَاءُ
Meaning: We then turned against Tamīm and entered a sacred month, while women from another people were among us as captives.
Milnā ʿalā Tamīm means turning against the tribe in a raid. Fa-aḥramnā means entering a sacred month here, rather than merely assuming the pilgrimage rite of iḥrām. Imāʾ here denotes enslaved or captive women in an early warfare context.
The verse expresses a claim within pre-Islamic martial boasting. Explaining the captivity does not endorse the practice as moral guidance.
