`Sayyiduna Uqbah bin Amir (may Allah be pleased with him) narrates from the Messenger of Allah (peace and blessings of Allah be upon him) that he (peace be upon him) said: The expiation for a vow is the same as the expiation for an oath. (That is, feeding ten needy people, or clothing ten needy people, or freeing a slave. If one is unable to do these, then fast for three days.)
