Divorcing a woman before consummating the marriage and then remarrying her and having children
A man married a virgin then divorced her before having intercourse with her, and married another woman then divorced that woman, and married the first woman again. Their marriage continued and now he has children from her. Is he considered sinful?
(Part No. 18; Page No. 391)
If the case is as you mentioned, he is not sinful at all. In addition, his marriage to the one whom he previously divorced is valid. May Allah grant us success. May peace and blessings be upon our Prophet Muhammad, his family, and Companions.
