What should a woman do who caused the death of her neighbors' chicken and left it in the sun, and did not inform them, knowing that the owner of the chicken has passed away, but her husband and heirs are still alive, so that her repentance may be complete?

The woman committed two sins: torturing an animal to death (based on the Hadith (definition) of the cat), and destroying a Muslim's property. She must repent for both actions and return the value of the destroyed property to the heirs of the deceased, without needing to tell them the story, while ensuring that the right reaches all heirs.
