Does the expiation (kaffarah) fall away from one who had intercourse with his wife during the daytime in Ramadan, then paid money for the expiation, then fasted for 80 days after about five years?

If you paid money while you were able to fast, that does not absolve you; rather, you must fast. This is the view of the majority of scholars who say that there must be an order among the expiation's components. They cite the agreed-upon Hadith of Abu Hurairah concerning the man who had intercourse with his wife while fasting. Since you fasted for sixty days thereafter, that suffices for the expiation.
