What are the consequences for someone who repents from stealing money from electronic gambling, and is he required to return it to its owner, knowing that disclosure may lead to problems?

Repentance from stealing someone else's money is commendable. Among its conditions is returning the stolen money to its owner, even if through indirect means, without the need to inform him that the thief was the one who took it. This is because what matters is that his right reaches him. The repentant thief must also advise the shop owner to prevent gambling in his establishment, as gambling is among the gravely forbidden acts.
