حَدَّثَنَا مُحَمَّدُ بْنُ جَعْفَرٍ حَدَّثَنَا شُعْبَةُ سَمِعْتُ عَبْدَ الْأَعْلَى يُحَدِّثُ عَنْ أَبِي جَمِيلَةَ عَنْ عَلِيٍّ رَضِيَ اللَّهُ عَنْهُ أَنَّ أَمَةً لَهُمْ زَنَتْ فَحَمَلَتْ فَأَتَى عَلِيٌّ النَّبِيَّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ فَأَخْبَرَهُ فَقَالَ لَهُ دَعْهَا حَتَّى تَلِدَ أَوْ تَضَعَ ثُمَّ اجْلِدْهَا
مسند امام احمد بن حنبل · Hadith 679
It was narrated from 'Ali that a slave woman of theirs committed zina and became pregnant. 'Ali went to the Prophet (PBUH) and told him. He said: "Leave her until she gives birth, then flog her."
