Does one expiation or two expiations become obligatory upon someone who swore an oath not to repeat an action for ten days, then swore an oath again not to repeat it for fifteen days, and then repeated it before the expiration of both periods?

If an oath is repeated concerning a single matter and the swearer breaks it, then only one expiation is required. This is because the jurisprudential rule states that similar matters with a single purpose are subsumed. This is the view held by Ibn Umar, Al-Hasan, Urwah, Ishaq, and others, who argue that since the breach is one, it necessitates only one expiation. Some scholars hold that multiple oaths necessitate multiple expiations, unless the intention of the second oath was repetition or emphasis. This is further confirmed when the period specified by the oath differs, as the first oath is then subsumed into the second, and the swearer is liable for only one expiation upon breaking the oath.
