Husband taking an oath that his wife will be unlawful for him if his son does not dine with them, and he did not
When his son returned from travel, he took an oath that his wife will be unlawful for him if his son would not dine with him. However, the son did not dine with him.
He asks about the ruling on saying so.
(Part No. 20; Page No. 113)
If the reality is as mentioned in the question, that he took an oath that his wife will be unlawful for him if his son would not dine with him that night when he came back from his journey, and his son refused to dine with him on that night, it will be a broken oath and the father has to offer a Kaffarah (expiation) for a broken oath, which is, feeding ten needy people half a Sa` (1 Sa`=3 kg. Approx.) of common food in his country, or clothing them, or freeing a Muslim slave. If he is unable to do so, he has to fast for three days. May Allah grant us success. May peace and blessings be upon our Prophet Muhammad, his family, and Companions.
