Is a marriage contracted between an engaged couple after a pregnancy resulting from their sexual intercourse considered a legitimate marriage (Shar'i)? What are its implications, what is the Shar'i ruling regarding the child, and is the child considered a child of Zina (illegitimate)?

Both the man and the woman must repent sincerely for committing the indecency, as the fiancée is considered a stranger to the suitor before the marriage contract. The subsequent marriage is deemed invalid, and the child resulting from this relationship is illegitimate and cannot be attributed to the man.
