Narrated An-Nu'man ibn Bashir:

The Prophet ﷺ 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 ﷺ فِي الرَّجُلِ يَأْتِي جَارِيَةَ امْرَأَتِهِ قَالَ
" إِنْ كَانَتْ أَحَلَّتْهَا لَهُ جُلِدَ مِائَةً وَإِنْ لَمْ تَكُنْ أَحَلَّتْهَا لَهُ رَجَمْتُهُ " .
