Because of Marriage People Who Become Unlawful to Marry

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 عليه السلام, 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.’”
