A woman deeming herself unlawful for her husband

Q: A wife said that if her husband did not return home in two months, he would be deemed unlawful for her unless he would provide her with a separate house away from his mother's. The husband returned after a long period of time. The family interfered (Part No. 20; Page No. 108) and obliged her to return to her husband and live with his mother in the same house. Are there any consequences for what she said and failed to abide by?

A: If the reality is as mentioned, she has to offer Kaffarah (expiation) for the oath she has broken. This Kaffarah is to emancipate a believing slave, feed ten Miskins (needy persons) each with one Sa` (1 Sa`=3 kg. Approx.), or provide them with clothing. If she cannot do any of these, she should observe Sawm (Fast) for three days. May Allah grant us success. May peace and blessings be upon our Prophet Muhammad, his family, and Companions.
