Sahih al-Bukhari 2232, 2233
حَدَّثَنِي زُهَيْرُ بْنُ حَرْبٍ، حَدَّثَنَا يَعْقُوبُ، حَدَّثَنَا أَبِي، عَنْ صَالِحٍ، قَالَ حَدَّثَ ابْنُ شِهَابٍ، أَنَّ عُبَيْدَ اللَّهِ، أَخْبَرَهُ أَنَّ زَيْدَ بْنَ خَالِدٍ وَأَبَا هُرَيْرَةَ رضى الله عنهما أَخْبَرَاهُ أَنَّهُمَا، سَمِعَا رَسُولَ اللَّهِ صلى الله عليه وسلم يُسْأَلُ عَنِ الأَمَةِ تَزْنِي وَلَمْ تُحْصَنْ قَالَ " اجْلِدُوهَا، ثُمَّ إِنْ زَنَتْ فَاجْلِدُوهَا، ثُمَّ بِيعُوهَا بَعْدَ الثَّالِثَةِ أَوِ الرَّابِعَةِ ".
Zuhayr ibn Harb narrated to me: Yaqub narrated to us: My father narrated to us, from Salih, who said: Ibn Shihab narrated that Ubayd Allah informed him that Zayd ibn Khalid and Abu Hurayra, may Allah be pleased with them both, informed him that they had heard the Messenger of Allah being asked about an enslaved woman who committed zina and had not been married. He said: “Flog her. Then, if she commits zina again, flog her. Then sell her after the third or the fourth time.”
Translation notes
The report explicitly leaves uncertain whether the sale follows the third or fourth occurrence. It does not state a flogging after that final occurrence.
