Is a husband's prayer against his wife for harm answered in Islamic law, especially after she confessed to him losing her virginity before marriage and causing family problems as a result, and is she entitled to seek divorce to relieve her husband and his family?

You must be mindful of Allah's blessings, such as repentance, a spouse, and a child, and increase your remembrance of Allah (dhikr) and gratitude (shukr), for the heart finds tranquility in the remembrance of Allah. The marriage is not invalid because the husband was not informed about the loss of virginity, unless this was a stipulated condition. The wife is not unjust to her husband or his family for not informing them, and the supplication of the husband's family made unjustly will not be answered. It was wrong to confess adultery to the husband and to consider informing his family; rather, one ought to conceal their own sins. The husband's family has no right to hold the wife accountable for a past sin from which she has repented. You must strive for a good relationship with your husband, be patient with his family, and respond to bad deeds with good ones. You must beware of Satan exaggerating matters, forget the past, and look forward to the future.
