What is the fate of a girl born from a pregnancy that occurred after the marriage contract (aqd al-qiran) but before the consummation (wedding night), and what is the mother's sin in this case?

If the marriage contract has been concluded and the husband is able to consummate the marriage with his wife, and she becomes pregnant and claims that the pregnancy is from him, and he confirms her claim, then the pregnancy is legitimate and the child will be theirs. However, if the husband denies paternity of the child, the child is not attributed to him and belongs to its mother, and they must be separated. It is advisable to avoid intercourse before the wedding if that is the customary practice, due to the potential prohibitions that may arise therefrom.
