Someone traveled for a long time and his wife gave birth to a baby during his absence? Is it permissible for such a husband to deny his fatherhood of the concerned baby, to divorce his wife because of this, or what should he do?
It is not permissible for the husband in question to deny such a baby unless he does so through Li`an (allegation of adultery against a wife, accompanied by mutual invoking of Allah’s Curse/Wrath if lying). It is worthy mentioning that Li`an is to be done in the court. However, if Li`an takes place, (Part No. 20; Page No. 340) separation between the two sides will happen and such a wife will never be lawful in marriage to the same husband. May Allah grant us success. May peace and blessings be upon our Prophet Muhammad, his family, and Companions.
