Woman marrying few weeks after having fornicated
13-11-2016 | IslamWeb
Question:
Assalaamu alaykum. One of our sisters got married six years ago and is with children. Unfortunately, she had sexual intercourse with another man about three weeks prior to the wedding ceremony. After the wedding and at the end of the month, she could not see her period and thus realized that something had happened. Two months later, she had a miscarriage and could not tell her husband exactly what had happened. However, six years later, she informed me and asked me to tell the husband what had happened, which I thus did. The husband had sympathy with her, forgave her, and asked her to seek for Allaah's forgiveness and mercy. My questions are: what is the fate of their marriage now? Is there anything they can do to remain a couple (wife and husband)? Wassalaamu alaykum.
Answer:
All perfect praise be to Allah, The Lord of the worlds. I testify that there is none worthy of worship except Allah and that Muhammad 
is His slave and Messenger.
What happened here is that this woman got married before Istibraa' (making sure that she was not pregnant) from Zina fornication. The jurists differed in opinion about the ruling of such marriage in this case; some of them are of the view that the marriage contract is valid, and others are of the view that this marriage is void.
Therefore, the marriage is valid based on the view of the scholars who consider it to be valid.
We should point out that this woman must sincerely repent to Allah fulfilling the conditions of sincere repentance, which have been highlighted in fatwas 86527 and 87903.
She must also beware of anything that could lead to temptation and committing Zina again, such as being in seclusion with non-Mahram (marriageable) men, forbidden mixing, and the like. She should not have told you or anyone else about having committed Zina because the Islamic Sharia commands us to conceal our sins.
Allah knows best.
