12. Muhammad ibn Yahya in a marfu‘ manner has narrated from Ishaq ibn ‘Ammar who has said the following: “This is the case of a man who marries a woman for a slave with his wife. He delivers them to her then the wife of the slave dies in the possession of the woman; then he divorces her before going to bed with her. Abu al-Hassan, al-Awwal عليه السلام, has said, ‘If he had appraised her for her on the day of marriage he then appraises the slave. He then counts the difference of the day of marriage which she must return to him, then he gives her one-half of what he has received back.’”
