Is one held accountable for knowing the ruling but not knowing what follows from it?

Question : Is it valid to argue, based on what happened to Adam (peace be upon him) when he was expelled from Paradise because he fell into what he was forbidden from, that one who knows the ruling is held accountable for violating it even if he does not know what follows from it, just as we said regarding the hadith about the one who engages in socializing during the day of Ramadan?

Answer : He said: No, he is not held accountable, because Allah said: because there is a punishment.
