وَحَدَّثَنِي مَالِكٌ، عَنْ نَافِعٍ، عَنْ صَفِيَّةَ بِنْتِ أَبِي عُبَيْدٍ، أَنَّهَا أَخْبَرَتْهُ أَنَّ عُمَرَ بْنَ الْخَطَّابِ قَالَ مَا بَالُ رِجَالٍ يَطَئُونَ وَلاَئِدَهُمْ ثُمَّ يَدَعُوهُنَّ يَخْرُجْنَ لاَ تَأْتِينِي وَلِيدَةٌ يَعْتَرِفُ سَيِّدُهَا أَنْ قَدْ أَلَمَّ بِهَا إِلاَّ قَدْ أَلْحَقْتُ بِهِ وَلَدَهَا فَأَرْسِلُوهُنَّ بَعْدُ أَوْ أَمْسِكُوهُنَّ ‏.‏ قَالَ يَحْيَى سَمِعْتُ مَالِكًا يَقُولُ الأَمْرُ عِنْدَنَا فِي أُمِّ الْوَلَدِ إِذَا جَنَتْ جِنَايَةً ضَمِنَ سَيِّدُهَا مَا بَيْنَهَا وَبَيْنَ قِيمَتِهَا وَلَيْسَ لَهُ أَنْ يُسَلِّمَهَا وَلَيْسَ عَلَيْهِ أَنْ يَحْمِلَ مِنْ جِنَايَتِهَا أَكْثَرَ مِنْ قِيمَتِهَا ‏.‏

Malik related to me from Nafi that Safiyya bint Abi Ubaydinformed him that Umar ibn al-Khattab said, "What is the matter withmen who have intercourse with their slave-girls and then leave them togo? No slave-girl comes to me whose master confesses that he has hadintercourse with her but that I connect her child to him, whether ornot he has practised coitus interruptus or left off from intercoursewith her." Yahya said that he heard Malik say, "What is donein our community about an umm walad who commits a crime is that hermaster is liable for what she has done up to her value. He does nothave to surrender her, and he cannot be made to bear more than hervalue for her crime." Translation Not Available
