The Prophet ﷺ said: “If a maid-servant commits adultery and it is proven, then let him (the master) flog her and not reproach her. Then if she commits adultery again, let him flog her and not reproach her. Then if she commits adultery a third time, let him sell her, even if only for a rope made of hair.”

قَالَ النَّبِيُّ ﷺ: «إِذَا زَنَتِ الأَمَةُ فَتَبَيَّنَ زِنَاهَا فَلْيَجْلِدْهَا وَلاَ يُثَرِّبْ، ثُمَّ إِنْ زَنَتْ فَلْيَجْلِدْهَا وَلاَ يُثَرِّبْ، ثُمَّ إِنْ زَنَتِ الثَّالِثَةَ فَلْيَبِعْهَا وَلَوْ بِحَبْلٍ مِنْ شَعَرٍ».

Messenger of Allah ﷺ was asked about the slave-girl, if she was a virgin and committed illegal sexual intercourse. The Prophet ﷺ said, "If she committed illegal sexual intercourse, lash her, and if she did it a second time, then lash her again, and if she repeated the third time, then sell her even for a hair rope." Ibn Shihab said, "I don't know whether to sell her after the third or fourth offense."

أَنَّ رَسُولَ اللَّهِ ﷺ سُئِلَ عَنِ الأَمَةِ إِذَا زَنَتْ وَلَمْ تُحْصِنْ قَالَ إِنْ زَنَتْ فَاجْلِدُوهَا ثُمَّ إِنْ زَنَتْ فَاجْلِدُوهَا ثُمَّ إِنْ زَنَتْ فَبِيعُوهَا وَلَوْ بِضَفِيرٍ قَالَ ابْنُ شِهَابٍ لاَ أَدْرِي بَعْدَ الثَّالِثَةِ أَوِ الرَّابِعَةِ
