"If he forced her, then she is free at his expense and he has to give her mistress a similar slave as a replacement. If she obeyed him in that, then she belongs to her mistress, and he has to give her mistress a similar slave as well."  

أَنَّ رَجُلاً غَشِيَ جَارِيَةً لاِمْرَأَتِهِ فَرُفِعَ ذَلِكَ إِلَى رَسُولِ اللَّهِ ﷺ فَقَالَ إِنْ كَانَ اسْتَكْرَهَهَا فَهِيَ حُرَّةٌ مِنْ مَالِهِ وَعَلَيْهِ الشَّرْوَى لِسَيِّدَتِهَا وَإِنْ كَانَتْ طَاوَعَتْهُ فَهِيَ لِسَيِّدَتِهَا وَمِثْلُهَا مِنْ مَالِهِ  

"The Prophet passed judgment concerning a man who had intercourse with his wife's slave woman: 'If he forced her, then she is free, and he has to give her mistress a similar slave as a replacement; if she obeyed him in that, then she belongs to him, and he has to give her mistress a similar slave as a replacement.'" (Using translation from Nasāʾī 3363)   

أَنَّ رَجُلًا وَقَعَ عَلَى جَارِيَةِ امْرَأَتِهِ فَرُفِعَ ذَاكَ إِلَى النَّبِيِّ ﷺ فَقَالَ إِنْ كَانَتْ طَاوَعَتْهُ فَهِيَ لَهُ وَعَلَيْهِ مِثْلُهَا لَهَا وَإِنْ كَانَ اسْتَكْرَهَهَا فَهِيَ حُرَّةٌ وَعَلَيْهِ مِثْلُهَا لَهَا  

[Machine] A man went out on a expedition and took with him a slave girl belonging to his wife. He had a relationship with her, and this matter was mentioned to the Prophet ﷺ . He said: "If he forced her (into a relationship), then she is free and he must give her a similar slave girl. But if she willingly submitted, then she is his slave girl and he must give her a similar slave girl." Isma'il (may Allah be pleased with him) narrated that a man was in an expedition.  

أَنَّ رَجُلًا خَرَجَ فِي غَزَاةٍ وَمَعَهُ جَارِيَةٌ لِامْرَأَتِهِ فَوَقَعَ بِهَا فَذُكِرَ لِلنَّبِيِّ ﷺ فَقَالَ إِنْ كَانَ اسْتَكْرَهَهَا فَهِيَ عَتِيقَةٌ وَلَهَا عَلَيْهِ مِثْلُهَا وَإِنْ كَانَتْ طَاوَعَتْهُ فَهِيَ أَمَتُهُ وَلَهَا عَلَيْهِ مِثْلُهَا وَقَالَ إِسْمَاعِيلُ مَرَّةً إِنَّ رَجُلًا كَانَ فِي غَزْوَةٍ  

[Machine] About the Prophet ﷺ regarding a man who had relations with his wife's slave girl: "If he forced her, she is free and he must give her the same as her value. And if she willingly submitted, she belongs to him and he must give her the same as her value."  

عَنِ النَّبِيِّ ﷺ فِي رَجُلٍ وَقَعَ عَلَى جَارِيَةِ امْرَأَتَهِ «إِنْ كَانَ اسْتَكْرَهَهَا فَهِيَ حُرَّةٌ وَعَلَيْهِ مِثْلُهَا وَإِنْ كَانَتْ طَاوَعَتْهُ فَهِيَ لَهُ وَلَهَا عَلَيْهِ مِثْلُهَا»  

[Machine] About the Prophet ﷺ regarding a man who had sexual intercourse with his wife's slave-girl, he said: "If he forced her to do so, then she is free, and he must free a slave-girl like her. But if she willingly agreed, then she is a slave-girl and he must free a slave-girl like her." This was narrated by Ma'mar from Qatadah.  

عَنِ النَّبِيِّ ﷺ فِي رَجُلٍ وَطِئَ جَارِيَةَ امْرَأَتِهِ فَقَالَ إِنِ اسْتَكْرَهَهَا فَهِيَ حُرَّةٌ وَلَهَا عَلَيْهِ مِثْلُهَا وَإِنْ كَانَتْ طَاوَعَتْهُ فَهِيَ أَمَةٌ وَلَهَا عَلَيْهِ مِثْلُهَا وَرَوَاهُ مَعْمَرٌ عَنْ قَتَادَةَ  

"عَنْ سَلَمَةَ بْن الْمُحَبِّقِ قَالَ: قَضَى رَسُولُ الله ﷺ فِى رَجُلٍ وَطِئَ جَارِيَةَ امْرَأَتِه: إِنْ كَانَ اسْتَكْرَهَها فَهِى حُرَّةٌ، وَعَلَيْهِ لِسَيِّدَتِها مِثْلُها، وَإنْ كَانَتْ طَاوَعَتْهُ فَهِى لَهُ، وَعَلَيْهِ لِسَيِّدتِهَا مِثْلُهَا".
