حَدَّثَنَا عَبْدُ اللَّهِ بْنُ مَسْلَمَةَ الْقَعْنَبِيُّ، حَدَّثَنَا مَالِكٌ، ح وَحَدَّثَنَا يَحْيَى بْنُ يَحْيَى، - وَاللَّفْظُ لَهُ - قَالَ قَرَأْتُ عَلَى مَالِكٍ عَنِ ابْنِ شِهَابٍ عَنْ عُبَيْدِ اللَّهِ بْنِ عَبْدِ اللَّهِ عَنْ أَبِي هُرَيْرَةَ أَنَّ رَسُولَ اللَّهِ صلى الله عليه وسلم سُئِلَ عَنِ الأَمَةِ إِذَا زَنَتْ وَلَمْ تُحْصِنْ قَالَ " إِنْ زَنَتْ فَاجْلِدُوهَا ثُمَّ إِنْ زَنَتْ فَاجْلِدُوهَا ثُمَّ إِنْ زَنَتْ فَاجْلِدُوهَا ثُمَّ بِيعُوهَا وَلَوْ بِضَفِيرٍ " . قَالَ ابْنُ شِهَابٍ لاَ أَدْرِي أَبَعْدَ الثَّالِثَةِ أَوِ الرَّابِعَةِ . وَقَالَ الْقَعْنَبِيُّ فِي رِوَايَتِهِ قَالَ ابْنُ شِهَابٍ وَالضَّفِيرُ الْحَبْلُ .
Abu Huraira reported that Allah's Messenger (ﷺ) was asked about the slave-woman who committed adultery and was not protected (married). He said:If she commits adultery, then flog her and if she commits adultery again, then flog her and then sell her even for a rope. Ibn Shihab said: I do not know whether he said this (his statement pertaining to the sale of slave-woman) at the third or the fourth time. Ibn Shihab said that the word dafir (used in the text) means rope
