Is it permissible to return stolen money in installments? What is the ruling on profiting from and consuming one's private wealth before returning stolen money? And can it be given to the thieving brother or needy relatives?

The questioner is obligated to return the money to its owner immediately. It is not permissible to return it in installments if it is possible to return it in one lump sum. If he cannot return it except by selling the shop, then he must do so. It is not permissible to give the money in charity as long as its owner is alive.
