رَوَى وَهْبُ بْنُ وَهْبٍ عَنْ جَعْفَرِ بْنِ مُحَمَّدٍ عَنْ أَبِيهِ عَلَيْهِ اَلسَّلاَمُ أَنَّهُ كَانَ يَقُولُ: "إِذَا قَتَلَتْ أُمُّ اَلْوَلَدِ سَيِّدَهَا خَطَأً فَهِيَ حُرَّةٌ وَ لاَ تَبِعَةَ عَلَيْهَا وَ إِنْ قَتَلَتْهُ عَمْداً قُتِلَتْ بِهِ".
Wahb ibn Wahb narrated from Imam Jafar ibn Muhammad Al-Sadiq (a.s) from his father, Imam Muhammad ibn Ali Al-Baqir (a.s) that Imam (a.s) used to say: "If a slave woman who has borne a child (umm Al-walad) kills her master by mistake, she becomes free and there is no liability upon her. However, if she intentionally kills him, she is to be executed for him."
