Question: Assalamu ‘alaykum,
I performed an expiation (60 consecutive fasts) for a contravention in Ramadan which didn’t require an expiation. Can I use this expiation I performed for another contravention which, this time, does require an expiation?
Answer: Assalamu alaikum wa rahmatullah,
One expiation (kaffara) suffices for all previous major contraventions which occurred during Ramadan fasts. You do not need to perform a separate expiation for each occurrence because a single one suffices as a penalisation and future deterrent [Shurunbulali, Maraqi al-Falah].
However, if a contravention occurred during the fasting hours in the month of Ramadan, and you performed the expiation thereafter, and then another major contravention occurred in a subsequent Ramadan, you would need to perform a second expiation because expiation do not apply retrospectively.
And Allah alone knows best.
