3. Abu Ali al-Ash’ariy has narrated from Muhammad ibn ‘Abd al-Jabbar and Muhammad ibn ‘Isma’il has narrated from al-Fadl ibn Shadhan all from Safwan from ‘Abd al-Rahman ibn al-Hajjaj who has said the following: “I once asked abu Ibrahim (a.s.), about the case of a man who married a woman during her waiting period because of ignorance; if she became unlawful for him forever. He (the Imam) said, ‘No, if marriage is because of ignorance he must marry her again after the waiting period is complete; people due to ignorance are sometimes forgiven even for an issue bigger than this.’ I then asked, ‘Of the two which ignorance is excused, ignorance of its unlawfulness or ignorance of her being in the waiting period?’ He (the Imam) said, ‘Of the two the ignorance which is easier is excused, and it is ignorance of the fact that Allah has made it unlawful because with it he cannot maintain precaution.’ I then asked, ‘Will he because of such ignorance be excused on the Day of Judgment?’ He (the Imam) said, ‘Yes, when her waiting period is complete he is excused if he marries her.’ I then asked, ‘What happens if one knows and the other is ignorant?’ He (the Imam) said, ‘The one who knowingly has done it can never return to his companion.’”

4. Ali ibn Ibrahim has narrated from his father from Ibn Abi ‘Umayr from Hammad from al-Halabiy who has said the following: “This is concerning my question before abu ‘Abd Allah (a.s.), about the case of a woman who is pregnant and her husband dies. She gives birth and marries before the passing of four months and ten days. He (the Imam) said, ‘If he has gone to bed with her, they must be separated from each other and she will be unlawful for him forever. She must complete the remaining of her waiting period and complete another waiting period from the end of that for three cycles of menses, but if he has not gone to bed with her, they must separated from each other and she must complete the remaining of her waiting period and he then is one of the people who can propose to her for marriage.’”

She gave birth and married before the passing of four months and ten days. He (the Imam) said, ‘If the one who has married has gone to bed with her, they must separate from each other and she is not lawful for him forever. She must complete the remaining of her first waiting period and complete another waiting period in future for three cycles of menses; but if he has not gone to bed with her, they must separate from each other and she must complete the remaining of her waiting period. He then is one of those who can propose to her for marriage.’”

They must separate from each other and she is not lawful for him forever. If he has not gone to bed with her she does not have any mahr (dower).”’
