What is the ruling on swearing an oath that Allah curses the swearer, cuts off their hand, or curses them, if a prohibited action is performed?

Primary text

If a person swears that if they commit a certain act, then 'May Allah degrade him' (Akhzahu Allah), or 'May Allah cut off his hand,' or 'May Allah curse him,' and they fulfill the condition (Hanith), no expiation is due upon them. This is the stated position of Ahmad, supported by 'Ata, Al-Thawri, Abu 'Ubayd, and the Ashab ar-Ra'y (the Companions of the School of Opinion). The basis for this ruling is that the oath does not necessitate disbelief (Kufr), making it analogous to the case where one swears they erased the Mus'haf.
