How can rights be returned to their owners in two cases: first, taking wood from a contractor without his knowledge; and second, benefiting from recharge cards after imitating women's voices, knowing that some of the rights holders are unknown or difficult to reach?

Whoever stole wood must return its value to its owner if he destroyed it, or the value of the benefit he gained from it if he did not destroy it but only used it. As for the recharge cards that were given as a result of deception by voice alteration, they do not need to be returned to their owners; rather, one must repent, seek forgiveness, and give charity equivalent to the value of these cards.
