4. Muhammad ibn Yahya has narrated from Ahmad ibn Muhammad from al-Hassan ibn Mahbub from ibn Bukayr and Ali ibn Ri’ab from Zurarah ibn ‘A‘yan who has said the following: “This is concerning my question before abu Ja’far (a.s.), about the case of a man who marries in Iraq a woman; then goes to al-Sham (Syria) and marries another there who is the sister of the one in Iraq. He (the Imam) said, ‘He must separate from the one in al-Sham and must not go close to the woman until waiting period of the woman in al-Sham is complete.’ I then asked, ‘What happens if one marries a woman then marries her mother in ignorance?’ He (the Imam) said, ‘Allah has exempted people in their ignorance.’ Then he (the Imam) said, ‘When he comes to know that she is her mother he must not go close to her as well as to her daughter until waiting period of the mother is complete and when waiting period of mother is complete marriage with daughter becomes lawful.’ I then asked, ‘What happens if the mother gives birth?’ He (the Imam) said, ‘He is his child and thus his son becomes brother of his wife.’”

5. Ali ibn Ibrahim has narrated from his father from ‘Isma’il ibn Marrar from Yunus who has said the following: “I read in the letter of a man to al-Rida’ (a.s.), that said, ‘I pray to Allah to keep my soul in service for your cause, if a man marries a woman in the manner of Mut‘ah for an appointed time which expires; if he can marry her sister before her sister completes her waiting period.’ He (the Imam) had written to him, ‘It is not lawful for him to marry before her waiting period is complete.’”

6. Muhammad ibn Yahya has narrated from Ahmad ibn Muhammad ibn ‘Isa from Muhammad ibn ‘Isma’il ibn Bazi’ from Muhammad ibn al-Fadl from abu al-Sabbah al-Kinaniy who has said the following: “This is concerning my question before abu ‘ Abd Allah (a.s.), about the case of a man whose wife divorces him in the manner of al-Khula‘ (payment for divorce); if it is permissible to propose marriage to her sister before her waiting period is complete. He (the Imam) said, ‘Since she has set herself free and there is no chance to go back, it is lawful for him to propose marriage to her sister.’ He (the narrator) has said that he (the Imam) was asked about the case of a man who had two sisters as his slave-girls. He goes to bed with one of them then he goes to bed with the other one. He (the Imam) said, ‘When he goes to bed with the other one, the first one becomes unlawful for him until the other one dies.’ I then asked, ‘What happens if he sells her?’ He (the Imam) said, ‘If he sells her because of a reason without anything in his mind about the other slave-girl, then I do not see it as harmful, but if he sells her so he can go to the first one, then it is not permissible.’”
