Narrated Salamah ibn al-Muhabbaq:

The Messenger of Allah (ﷺ) made a decision about a man who had intercourse with his wife's slave-girl as follows. If he forced her, she is free, and he shall give her mistress a slave-girl similar to her; if she asked him to have intercourse voluntarily, she will belong to him, and he shall give her mistress a slave-girl similar to her. Abu Dawud said: This tradition has been transmitted by Yunus b. 'Ubaid, 'Amr b. Dinar, Mansur b. Zadhan and Salam from al-Hasan to the same effect. But yunus and Mansur did not mention Qabisah.

حَدَّثَنَا أَحْمَدُ بْنُ صَالِحٍ، حَدَّثَنَا عَبْدُ الرَّزَّاقِ، أَخْبَرَنَا مَعْمَرٌ، عَنْ قَتَادَةَ، عَنِ الْحَسَنِ، عَنْ قَبِيصَةَ بْنِ حُرَيْثٍ، عَنْ سَلَمَةَ بْنِ الْمُحَبَّقِ، أَنَّ رَسُولَ اللَّهِ صلى الله عليه وسلم قَضَى فِي رَجُلٍ وَقَعَ عَلَى جَارِيَةِ امْرَأَتِهِ إِنْ كَانَ اسْتَكْرَهَهَا فَهِيَ حُرَّةٌ وَعَلَيْهِ لِسَيِّدَتِهَا مِثْلُهَا فَإِنْ كَانَتْ طَاوَعَتْهُ فَهِيَ لَهُ وَعَلَيْهِ لِسَيِّدَتِهَا مِثْلُهَا ‏.‏ قَالَ أَبُو دَاوُدَ رَوَاهُ يُونُسُ بْنُ عُبَيْدٍ وَعَمْرُو بْنُ دِينَارٍ وَمَنْصُورُ بْنُ زَاذَانَ وَسَلاَّمٌ عَنِ الْحَسَنِ هَذَا الْحَدِيثَ بِمَعْنَاهُ لَمْ يَذْكُرْ يُونُسُ وَمَنْصُورٌ قَبِيصَةَ ‏.‏
