A Woman Swears to Her Children,Then They Disobey Her

Question :

I have children and often I swear to them that they should not do such-and-such, but they do not obey my orders. Must I atone for a broken oath in these circum- stances?

Answer:

If you swore an oath about them, or others, intending that they should do something, or that they should not do something, then they disobeyed you, you must atone for an unfulfilled oath, according to the Words of Allah, Most Glorified:
"Allah will not punish you for what is unintentional in your oaths, but He will punish you for your deliberate oaths; for its expiation (a deliberate oath) feed ten Masäkin (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).

Likewise, if you swore to do something or to abandon something, then afterwards you thought that it was in your best interest to contradict that, then there is no objection to breaking your oath and performing the above-mentioned atonement, in accordance with the saying of the Prophet ﷺ:

"If you swore an oath, then saw something better than it, atone for your oath and do the thing which is better."
