What is the ruling on one who repents with a comprehensive repentance then insists on some sins? Is this repentance valid for all sins or for some of them?

The repentance of this person is valid and accepted — God willing — unless they are persisting in specific sins, in which case they must repent from them. If they know these sins, they should make a specific repentance. If they are unaware of them or have forgotten them, they should make a general repentance. Repenting from one sin while persisting in others is valid according to the majority of scholars, and they must hasten to repent from what they have not yet repented from.
