Hadiths on eating and drinking while forgetful in obligatory and voluntary fasts

Question:
He says: Honorable Shaykh, may Allah grant you success, are the hadiths on eating and drinking while forgetful general for both obligatory and voluntary fasting?

Answer:
Without a doubt, they are general for the obligatory and the voluntary. The forgetful person is not attributed with an action, just as the coerced person is not attributed with an action. He does not know that he ate or drank voluntarily and with intention. Yes.
