عَنْ عَلِيٍّ رَضِيَ اللَّهُ عَنْهُ أَنَّ أَمَةً لَهُمْ زَنَتْ فَحَمَلَتْ فَأَتَى عَلِيٌّ النَّبِيَّ صَلَّى اللَّهُ عَلَيْهِ وَآلِهِ وَسَلَّمَ فَأَخْبَرَ فَقَالَ لَهُ دَعْهَا حَتَّى تَلِدَ وَتَضَعَ ثُمَّ اجْلِدْهَا
It is narrated from Sayyiduna Ali (may Allah be pleased with him), he says: One of his slave girls committed adultery and because of that she became pregnant. I went to the Noble Prophet (peace and blessings be upon him) and informed him of this. The Prophet (peace and blessings be upon him) said: Leave her until she gives birth, then carry out the prescribed punishment on her.
