What is required of one who wishes to retract his oath?

Question:
May Allah reward you. We are taking this call from Madinah, Abu Khalid. Peace be upon you. Peace be upon you, my brother. Please, state your question, may Allah preserve you. I had made photocopies of some documents for my sisters. The copies were incomplete, not full. So I went to the shop and said, "Why didn't you tell me the documents were incomplete?" So I swore that I would not photocopy them. Is there anything required of me if I go and have them copied? Yes. Brother Abu Khalid from Madinah, the honorable Shaykh, asks: He swore not to photocopy documents for his sisters, so is there anything required of him if he goes to the shop and has them copied for them?

Answer:
Yes, he goes and has them copied, and he owes an expiation for the oath. He owes an expiation for the oath. He feeds ten poor people, or clothes ten poor people, or fasts for three days. If he is unable to feed, clothe, or free a slave, he moves to fasting. Yes.
