Sahih Muslim 1703c
Abu Huraira reported that Messenger of Allah 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 it 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.
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 ﷺ 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 .
