Are the heirs of the deceased debtor obligated to pay off his remaining debt, knowing that some creditors, including the heirs themselves, refused the government's repayment of the debt installments and insisted on receiving the full amount?

The state's declaration of insolvency does not waive the debts of the insolvent. These debts remain his responsibility until they are paid, based on the Prophet's (peace be upon him) saying: "On the hand is what it has taken until it renders it back." What the government has paid to debtors is a donation from it. For those who accepted it, the debtor's responsibility is cleared. For those who did not accept it, their right remains, and the debtor's responsibility is not cleared except by paying his debt. If the deceased left behind enough to cover his debt, it is obligatory for the heirs to pay it before distributing the inheritance. If the inheritance is insufficient, it is recommended for them to pay on his behalf to clear his responsibility.
