“My father Ja’far ibn Muhammad as-Sadiq (MGB) was asked about women having intercourse with whom the Honorable the Exalted God has declared unlawful in the Holy Quran, and women having intercourse with whom the Prophet of God (MGB) has declared unlawful in his traditions. He (MGB) replied, ‘There are thirty-four groups of women with whom having intercourse has been forbidden. Seventeen cases have been declared forbidden in the Holy Quran, and seventeen cases have been declared forbidden in the traditions. What has come in the Quran is as follows. The first case is adultery as the Honorable the Exalted God has says, ‘Nor come nigh to adultery…’ The second case is marrying women whom one’s father has married as the Honorable the Exalted God says, ‘And marry not women whom your fathers married…’ And the other cases are as follows, ‘‘Prohibited to you (For marriage) are:- Your mothers, daughters, sisters; father’s sisters, mother’s sisters; brother’s daughters, sister’s daughters; foster-mothers (who gave you suck), foster-sisters; your wives’ mothers; your step-daughters under your guardianship, born of your wives to whom ye have gone in,- no prohibition if ye have not gone in;- (Those who have been) wives of your sons proceeding from your loins; and two sisters in wedlock at one and the same time, except for what is past;’And the other cases also include women in their period of menstruation as the Honorable the Exalted God says, ‘And do not approach them until they are clean.’And the other cases also include associating with women while we are in retreat in the mosque as the Honorable the Exalted God says, ‘But do not associate with your wives while ye are in retreat in the mosques.’The cases that have been declared forbidden in the traditions are as follows. The first case is having intercourse during the days of the month of Ramazan. The second is marrying with a women who has taken the oath of condemnation after she has taken it. The third case is marrying women during the period of prohibition ; having intercourse while in the state of ritual consecration (Ihram); marrying familiar ones to whom you are forbidden to marry (since that would constitute incest); marrying a woman who has been divorced by Zihar before the payment of expiation ; marrying unbelieving women ; for a man to ever again marry a woman after he has divorced her nine times ; marrying a slave after marrying a free woman ; marrying your wife’s paternal or maternal aunts ; marrying a slave girl without the consent of her master; marrying a slave girl by a man who can afford to marry a free woman; marrying a captured female slave before her being assigned to be in someone’s possession; marrying an unbelieving woman ; having sex with a bought female slave before her being purified by Istebra ; and having sex with a ransomed slave woman after some of the ransom money has been paid.’”
