Sunan Abi Dawud, Book 38, Hadith 4444 (USC-MSA) ⓘ
Narrated An-Nu'man ibn Bashir: The Prophet said: about a man who had (unlawful) intercourse with his wife's slave girl: If she made her lawful for him, he will be flogged one hundred lashes; if she did not make her lawful for him, I shall stone him.
حَدَّثَنَا مُحَمَّدُ بْنُ بَشَّارٍ، حَدَّثَنَا مُحَمَّدُ بْنُ جَعْفَرٍ، عَنْ شُعْبَةَ، عَنْ أَبِي بِشْرٍ، عَنْ خَالِدِ بْنِ عُرْفُطَةَ، عَنْ حَبِيبِ بْنِ سَالِمٍ، عَنِ النُّعْمَانِ بْنِ بَشِيرٍ، عَنِ النَّبِيِّ صلى الله عليه وسلم فِي الرَّجُلِ يَأْتِي جَارِيَةَ امْرَأَتِهِ قَالَ " إِنْ كَانَتْ أَحَلَّتْهَا لَهُ جُلِدَ مِائَةً وَإِنْ لَمْ تَكُنْ أَحَلَّتْهَا لَهُ رَجَمْتُهُ " .
