Expiation for an oath when breaking a vow regarding a wedding

Question:
This questioner, Abdulrahman, says: My brother committed to performing a vow of abstinence for me, and I swore by Allah more than seven times, but I swore by Allah and he also wants to do so. After that, there was some anger, which forced me to agree to his vow of abstinence and to enter upon him. Do I owe an expiation for those oaths?

Answer:
Yes, if you swore that he would not perform the wedding, and then you saw his distress and allowed him to go ahead with the wedding, you owe the expiation for an oath, because you broke the oath. So you owe the expiation for an oath. And this is the best course of action. The best thing is that you break the oath and agree to his wedding to comfort him, and you perform the expiation for an oath. The expiation is feeding ten poor people, giving each poor person half a sa' (a dry measure of about 3 kg) of food, or clothing ten poor people, giving each poor person a thobe, or freeing a slave, freeing a slave from the people of the Book. If you cannot find the means to do any of these, then you fast for three days. Yes.
