It is permissible to have intercourse with a female captive after it is established that she is not pregnant, and if she has a husband, then her marriage is annulled when she is captured
وَحَدَّثَنَا أَبُو بَكْرِ بْنُ أَبِي شَيْبَةَ، وَمُحَمَّدُ بْنُ الْمُثَنَّى، وَابْنُ، بَشَّارٍ قَالُوا حَدَّثَنَا عَبْدُ، الأَعْلَى عَنْ سَعِيدٍ، عَنْ قَتَادَةَ، عَنْ أَبِي الْخَلِيلِ، أَنَّ أَبَا عَلْقَمَةَ الْهَاشِمِيَّ، حَدَّثَ أَنَّ أَبَا سَعِيدٍ الْخُدْرِيَّ حَدَّثَهُمْ أَنَّ نَبِيَّ اللَّهِ صلى الله عليه وسلم بَعَثَ يَوْمَ حُنَيْنٍ سَرِيَّةً . بِمَعْنَى حَدِيثِ يَزِيدَ بْنِ زُرَيْعٍ غَيْرَ أَنَّهُ قَالَ إِلاَّ مَا مَلَكَتْ أَيْمَانُكُمْ مِنْهُنَّ فَحَلاَلٌ لَكُمْ وَلَمْ يَذْكُرْ إِذَا انْقَضَتْ عِدَّتُهُنَّ .
Abu Sa'id al-Khudri (Allah be pleased with him) reported that Allah's Messenger (ﷺ) sent a small army. The rest of the hadith is the same except this that he said: Except what your right hands possess out of them are lawful for you; and he did not mention" when their 'idda period comes to an end".
