Is it obligatory for one who has sworn an oath to do something and then sees a better option to expiate the oath first before doing the better thing?

Question:
May Allah reward you, Honorable Shaykh. This questioner says: If a person swears an oath and then sees a better option and wants to expiate the oath, the question is: Does he do the better thing and break the oath? Or is it necessary, as you say, may Allah grant you success, if a person swears and sees a better option and wants to expiate, does he do the better thing and expiate, or must he expiate first and then do the better thing?

Answer:
Both are mentioned in the narrations: that one performs the expiation first and then does the better thing, or does the better thing first and then expiates. Both are permissible. The believer expiates.
