The ruling on one who swears not to do something, while another swears that he should do it

Question:
The questioner says in his second question: “May Your Eminence, I went to one of my friends, and I swore by the haram that I would not sit with him at this time. He also swore by the haram that I should sit. We swore at the same time. What must we do?”

Answer:
The one whose wish was not fulfilled owes the expiation. The haram carries the ruling of an oath. So if one says, “The haram is upon me if I sit,” and the other says, “The haram is upon me if you sit,” the one whose desired outcome did not happen owes the expiation. For example, one says, “The haram is upon me if I eat,” and the other says, “The haram is upon me if you eat.” Or one says, “The haram is upon me if you drink coffee,” and the other says, “The haram is upon me if I drink coffee.” The one whose oath was fulfilled owes nothing, and the one whose oath was not fulfilled owes the expiation.
So if one says, “The haram is upon me if I drink coffee,” and he drinks coffee, he owes the expiation. If he says, “The haram is upon me if I have lunch,” and then he has lunch, he owes the expiation, and so on. It is the expiation of an oath: feeding ten poor people, or clothing them. For each poor person, it is half a sa’ of dates, or rice, or wheat. Its ruling is the ruling of an oath. Yes.
