How many oaths must be fulfilled in the case of swearing not to do something specific, then swearing not to break the first oath, then swearing not to break the second oath?

If someone swears to do something or to refrain from doing something, and swears that he will not break his oath, then he breaks it, he owes two expiations: an expiation for his original oath, and an expiation for breaking his oath not to break it. If he then swears not to violate the second oath, it appears that this does not require an additional expiation because it is a confirmation.

The Hanbali school of thought holds that if oaths are repeated and broken before expiation is performed, only one expiation is required. However, it is more cautious to pay two expiations, in accordance with the opinion of the majority of scholars, if this does not cause hardship. Excessive swearing is disliked.
