Swearing not to give the neighbor food but the wife then gives it

A: If the reality is as mentioned, the man has to offer a Kaffarah (Expiation) for a broken oath. Allah (Glorified and Exalted be He) has mentioned its description in His Saying, Allâh will not punish you for what is unintentional in your oaths, but He will punish you for your deliberate oaths; for its expiation feed ten Masâkîn (poor persons), on a scale of the average of that with which you feed your own families, or clothe them or manumit a slave. But whosoever cannot afford (that), then he should fast for three days. That is the expiation for the oaths when you have sworn. May Allah grant us success. May peace and blessings be upon our Prophet Muhammad, his family, and Companions.
