Shafaqna – (Shia International News Association) – The Grand Ayatollah Sistani answered some questions regarding pre-marital sex and adultery. According to Shafaqna the questions and answers are as follows:
Question: A man lived with a woman whom he intended to marry and also had sex with her without entering into a marriage contract (‘aqd); thereafter he married her in the proper religious way. Is their co-habitation before the ‘aqd considered marriage in the eyes of religious law? Does the subsequent ‘aqd have retroactive effect? What will be the status of the children born before the ‘aqd?
Answer: In [an Islamic] marriage, the spousal relationship is established by the verbal expression of the proposition and the acceptance. More over no action or deed that reflects the intention of marriage can be a substitute for the spoken words. Consequently, the marriage mentioned in the question is not valid except after the pronouncement of the religious marriage formula that does not have any retroactive effect.
As for the children, they will be considered legitimate if the parents did not know the law [requiring the ‘aqd] because their relationship will be classified as “wat’i bis-shubha”. But if both were aware of the law, their relationship is considered adulterous. Consequently the children will be deemed illegitimate. However, if only one knew about the law without the other, the children will be deemed legitimate in relation to the ignorant parent only.
Question: If an unmarried girl and an unmarried boy have had pre-marital sex, are they allowed to enter marriage contract with each other?
Answer: Yes, they are allowed.
Question: If a married woman commits adultery with a man, what would be your ruling about them.
Answer: The woman becomes permanently haram for him.
Question: If a Muslim woman commits adultery, is it permissible for her husband to kill her?
Answer: Based on obligatory precaution, it is not permissible for him to kill her, even if he sees her in the act of committing adultery.
