What is the obligation of one who took forbidden wealth and then repented?

Question:
This is a questioner from the Arab Republic of Egypt. He says: I am a person who has repented to Allah with a sincere repentance, and I have acquired a sum of wealth through an un-Islamic means. It is impossible for me to return this wealth to its owners because they have died. If I give it in charity, what is the position of the recipient if he knows that this wealth is forbidden? Should I inform him of that? And is it permissible for me to give this wealth in charity to my family?

Answer:
It is obligatory for you to return it to the heirs. You give it to the heirs of the deceased, if he has heirs, you give it to them. As for if he has no heirs, or you do not know them, or you do not know their address, you give it in charity to the poor, and you do not inform them. You give it in charity to the poor and do not tell them that it is such and such. The conscience is cleared with the repentance, and praise be to Allah.
