Is it permissible to pay a sum of money owed to the state in monthly installments through a charitable committee, knowing that no money is currently available except what was taken as a Tawarruq loan from an Islamic bank for marriage, and that this money was taken out of ignorance and repentance has been made for it?

It has been previously clarified that your repentance from [acquiring ill-gotten] money and your effort to return it are appreciated. There is no harm in authorizing a charitable organization to recover it and deliver it to its rightful owner. You can pay it from your saved funds, and the fact that it came from a Tawarruq transaction does not prevent you from using it to pay off a debt.
