The ruling on one who swore to abandon a sin and then returned to it

Question:
His last question says: I swore by placing my hand on the Book of Allah that I would abandon a specific sin, and I actually did abandon it, but it happened that I returned to it a second time. My question: Do I owe an expiation? I hope you will inform me. May Allah reward you with good.

Answer:
You must perform both repentance and the expiation. Repentance to Allah, if it was a sin; if the act was a sin, and you owe the expiation—the expiation for an oath—which is feeding ten poor people, or clothing them. Feeding ten means providing them with a dinner, or if not, a breakfast, or giving them half a sa' (a dry measure of about 3 kg) of dates, or rice, or wheat, and it is better to include a condiment with it. Or you may clothe them with a garment that suffices them for prayer, such as a shirt, or a lower garment and an upper garment for each one. Or you may free a slave if you are able. If you are unable to do any of the three, you must fast for three days. This is the expiation for an oath. Yes.
