The ruling on one who swears not to do something and then does it

Question:
He says: I swore on a certain day not to eat a particular food, but due to dire necessity I ate from this food that I had sworn not to eat. What is the advice?
Please guide us, may Allah reward you with good.

Answer:
You only have to pay the expiation for an oath, and praise be to Allah, the expiation for an oath. It is feeding ten poor people, or clothing them. Ten is the number of your fingers. You give each person half a sa' (a dry measure of about 3 kg), from the sa' of the Prophet (peace and blessings be upon him), of the staple food of the land, such as dates, rice, wheat, barley, raisins, or the like. If you feed them, or if you clothe them, giving each person a shirt or a lower garment and a cloak, that is sufficient. And if you host them for dinner or lunch in your house, that is sufficient for ten, and praise be to Allah. The amount is approximately one and a half kilograms by weight, which is close to half a sa'. Yes.
