Return the jewelry to her stepmother

Q: My father brought some goods into the house. He thought that they were Halal (lawful). However, without explaining the way these goods were gotten, I am sure that they are Haram (prohibited). Thus, I hope that your Eminence can help me get rid of such goods. I am ready to do whatever you order me to do. Should I take the concerned goods out of the house? Should I give them as charity on behalf of the people to whom they are due? Should I give their value to charity? Regarding my father, what should he do? Istighfar (seeking forgiveness from Allah) or Tawbah (repentance to Allah)?

(Part No. 15; Page No. 343) A: In the case that you are sure that having such goods is Haram and you know the people to whom they are due, you have to return the goods to them. However, in the case that you do not know them, you have to give the concerned goods as charity on their behalf. On the other hand, your father has to do Tawbah and Istighfar. May Allah grant us success. May peace and blessings be upon our Prophet Muhammad, his family, and Companions.
