Abu Sa'id al-Khurdi traced to the Prophet (ﷺ) the following statement regarding the captives taken at Autas, “There must be no intercourse with a pregnant woman till she gives birth to her child, or with one who is not pregnant till she has had one menstrual period.” Ahmad, Abu Dawud and Darimi transmitted it.

عَن أبي سعيدٍ الخدريِّ رَفْعَهُ إِلَى النَّبِيِّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ قَالَ فِي سَبَايَا أَوْطَاسٍ: «لَا تُوطَأُ حَامِلٌ حَتَّى تَضَعَ وَلَا غَيْرُ ذَاتِ حَمْلٍ حَتَّى تَحِيضَ حَيْضَةً» . رَوَاهُ أَحْمَدُ وَأَبُو دَاوُدَ وَالدَّارِمِيُّ
