Swearing to abandon a lawful thing

A: Anyone who swears to abandon something permissible such as the furnishings in question should make Kaffarah (expiation) for breaking their oath before using this item. The Kaffarah is to feed ten needy persons, each with half a Sa` (1 Sa`=3 kg. Approx.) of food or to clothe them each with a piece of clothing or to free a believing slave. If these acts are not available, a Muslim should fast for three days. If the restaurant owner authorized by the oath-taker has expiated (Part No. 23; Page No. 122) by feeding ten needy persons, this would be sufficient, praise be to Allah.It should be known to the restaurant owner that the Kaffarah is to feed ten needy persons; it is not sufficient to feed just one person ten times or two persons five times. The specification of the number ten is clear when Allah (Glorified be He) says: 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. And protect your oaths (i.e. do not swear much). Thus Allâh make clear to you His Ayât (proofs, evidence, verses, lessons, signs, revelations, etc.) that you may be grateful. May Allah grant us success. May peace and blessings be upon our Prophet Muhammad, his family, and Companions.
