Is expiation necessary for an oath not to accept a gift, knowing that it was taken with the intention of giving it away in charity?

If, by the oath, you intended not to take the gift for ownership or as charity, and then you took it, you must expiate your oath. However, if your intention was only not to take it for ownership, it is permissible for you to take it for charitable giving, and no expiation is due, for oaths are based on intention.
