The ruling on one who swears an oath by saying, “May the anger of Allah be upon me if I do such-and-such”?

Question : May Allah reward you, Honorable Shaykh, and benefit us with your knowledge. The questioner says: A man swore to something and said, “May the anger of Allah be upon me if I do such-and-such,” but he did it afterward. What is required of him? Is there an expiation?

Answer : Yes, he owes the expiation for an oath, because by saying “May the anger of Allah be upon me if I do it,” his intention was to refrain from it, not that he intended for the anger of Allah to befall him. But because of the strong resolve in his heart, he said, “May the anger of Allah be upon me if I do such-and-such.” So, if he did it, what must he do? He must perform the expiation for an oath, and he must also repent and not commit such an oath again.
