Is it obligatory to return stolen money to its owners who are characterized by fraud, deception, and sorcery, or is it permissible to donate it to the poor?

Theft is one of the major sins, necessitating repentance and the return of stolen goods to their owner, as Allah states: "As for the thief, male or female, cut off their hands as a recompense for what they have earned, a deterrent from Allah. And Allah is Almighty, All-Wise." And as the Prophet, peace and blessings be upon him, said: "The hand is responsible for what it took until it returns it." The money can be returned discreetly, and it is not permissible to give it to another person.
