2. Muhammad ibn Yahya has narrated from Ahmad ibn Muhammad from Muhammad ibn ‘Isma’il who has said the following: “I once asked al-Rida’, ‘Alayhi al-Salam, about the case of a man who had a slave-girl and he kissed her; if she was lawful for his sons. He (the Imam) asked, ‘Was it with lust?’ I replied, ‘Yes, it was with lust.’ He (the Imam) said, ‘He then has left nothing if he has kissed with lust.’ He (the Imam) then initiating said, ‘If he makes her bare and looks at her with lust she becomes unlawful to marry for his father and his son.’ I then asked, ‘What happens if he looks at her body?’ He (the Imam) said, ‘If he looks at her vagina and body with lust she becomes unlawful for him.’”

3. Ali ibn Ibrahim has narrated from his father from ibn abu ‘Umayr from Jamil ibn Darraj who has said the following: “This is concerning my question before abu ‘Abd Allah, ‘Alayhi al-Salam, about the case of a man who looks at a slave-girl whom he wants to buy; if she is lawful for his son. He (the Imam) said, ‘Yes, she is lawful unless he has looked at her private organs.”’

4. Muhammad ibn Yahya has narrated from Ahmad ibn Muhammad from Ali ibn al-Hakam from ‘Abd Allah ibn Yahya al-Kahiliy who has said the following: “Once abu ‘Abd Allah, ‘Alayhi al-Salam, was asked, when I was with him (the Imam), about the case of a man who bought a slave-girl but did not touch her. His wife commanded his son, who was ten years old, to fall on her (for sexual intercourse) and he did it, now what do you say about it. He (the Imam) said, ‘The boy has sinned as well as his mother and it is not permissible for the father, after his son’s going near her, to fall on her.’ I then asked him (the Imam) about the case of a man who has a slave-girl and his father places his hand on her with lust or looks where it is not permissible to look with lust. He (the Imam) disliked his son’s touching her.’”

5. Muhammad ibn ‘Isma’il has narrated from al-Fadl ibn Shadhan from ibn abu ‘Umayr from Rib’iy ibn ‘Abd Allah from Muhammad ibn Muslim who has said the following: “Abu ‘Abd Allah, ‘Alayhi al-Salam, has said, ‘If a man makes a slave-girl bare and places his hand on her she becomes unlawful for his son.’”

6. Abu Ali al-Ash’ariy has narrated from Muhammad ibn ‘Abd al-Jabbar from Safwan ibn Yahya from ibn Muskan from al-Hassan ibn Ziyad from Muhammad ibn Muslim who has said the following: “This is concerning my question before abu ‘Abd Allah, ‘Alayhi al-Salam, about the case of a man who has married a woman and has touched her. He (the Imam), ‘Alayhi al-Salam, said, ‘She is unlawful to his father and her mahr (dower) is obligatory.’”

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, ‘Alayhi al-Salam, 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.

8. A number of our people have narrated from Sahl ibn Ziyad from Ahmad ibn Muhammad from ibn abu Nasr from Hammad ibn ‘Uthaman from Murazim who has said the following: “I once heard abu ‘Abd Allah, ‘Alayhi al-Salam, saying, when he (the Imam) was asked about the case of a woman who commanded her son to fall on the slave-girl of his father and he did, ‘She has sinned and so has her son and certain ones of these people asked me about it and I said, “You can keep her because unlawful does not make lawful ones unlawful.’””
