Is a general repentance sufficient to expiate all sins, or is a specific repentance required for each sin?

If one repents with a general repentance, that is sufficient. Yes. And if he also says the well-known supplication for seeking forgiveness: “O Allah, I seek Your forgiveness for what I do not know,” that is also good. Does it expiate these? Yes, it expiates them. If it is permissible for a debtor to be absolved of a vague, unknown right owed to a human being, and that absolves him, what about the right of Allah? But what if he does not remember? Yes, if he does not remember, but in the prayer he says, “I seek Allah’s forgiveness for every sin,” that is sufficient.
