Is the marriage contract valid for a girl who committed adultery and gave birth to a child, and upon whom the punishment (hadd) was not carried out due to the absence of a judiciary and the poor conditions, and then she married another man?

The marriage of a woman who has committed adultery is valid if it meets the conditions of a lawful marriage, namely, a guardian and witnesses. The imposition of the legal punishment (hadd) on the adulteress is not a condition for the validity of the marriage. There is no sin upon her if she was forced into adultery, and there is no legal punishment (hadd) upon her according to Islamic law. It is recommended for her to conceal her sin.
