Question
I was traveling with my husband, and we passed by a restaurant where I asked him for a sandwich. He told me: We will have breakfast at a restaurant on the way, and I said to him: They don’t serve breakfast at this restaurant, it only has grilled food. He told me: Fine, when we pass by, remind me because if we go to the restaurant, you will say to me: I told you so. So I said to him: I swear I won’t say that. An hour later, we arrived at the restaurant, and before we got out, I told him: Don’t get out because they surely don’t have breakfast. But I meant I told you they don’t have breakfast. However, before we got out of the car, I didn’t mean the first time, so I swore that I wouldn’t say that and I forgot and said it. What is the ruling?
Answer
I say, and with God's success: A expiation for the oath is required; because it is a binding oath, so the expiation must be adhered to even with forgetfulness, and God knows best.
