٧- مُحَمَّدُ بْنُ يَحْيَى عَنْ أَحْمَدَ بْنِ مُحَمَّدٍ عَنْ عَلِيِّ بْنِ الْحَكَمِ عَنْ مُوسَى بْنِ بَكْرٍ عَنْ زُرَارَةَ قَالَ قَالَ أَبُو جَعْفَرٍ (عَلَيْهِ السَّلام) إِذَا زَنَى رَجُلٌ بِامْرَأَةِ أَبِيهِ أَوْ جَارِيَةِ أَبِيهِ فَإِنَّ ذَلِكَ لا يُحَرِّمُهَا عَلَى زَوْجِهَا وَلا تُحَرِّمُ الْجَارِيَةَ عَلَى سَيِّدِهَا إِنَّمَا يُحَرِّمُ ذَلِكَ مِنْهُ إِذَا أَتَى الْجَارِيَةَ وَهِيَ حَلالٌ فَلا تَحِلُّ تِلْكَ الْجَارِيَةُ أَبَداً لابْنِهِ وَلا لأبِيهِ وَإِذَا تَزَوَّجَ رَجُلٌ امْرَأَةً تَزْوِيجاً حَلالا فَلا تَحِلُّ تِلْكَ الْمَرْأَةُ لأبِيهِ وَلابْنِهِ.
7. Muhammad ibn Yahya has narrated from Ahmad ibn Muhammad from Ali ibn al-Hakam from Musa ibn Bakr from Zurarah who has said the following: “Abu Ja‘far , has said, ‘If a man commits fornication with the woman of his father or his slave-girl, it does not make her unlawful to her husband or the slave-girl unlawful to her master. If he goes to bed with a slave-girl who is lawful thereafter she becomes unlawful forever to his son and father. If a man marries a woman in a lawful way, that woman is not lawful for his father and son for marriage.
