How would a husband and a wife repent if they committed "Zina" before their marriage? Do they have to remarry?
Praise be to Allah, the Lord of the Worlds; and blessings and peace be upon our Prophet Muhammad and upon all his Family and Companions.
Basically, marrying a person who committed Zina is not permissible till he/she makes repentance towards Allah. In addition, to repent a woman who has committed Zina should wait until a menstrual period to confirm that she is not conceived from that Zina. This is only to protect mankind from mischief, bad consequences, and the lineage from being mixed, etc. After making sincere repentance the two people who committed Zina may get married. If it happened that they married before making repentance and after that they repent in this case the marriage contract is valid and they do not need to renew it. But, marrying before repentance is a great sin.
Allah knows best.
