Are the debts owed by the deceased father's company for buying and selling considered part of the father's debts, and should they be promptly settled, or can they remain under the company's system, and does anything remain owed by the father if an agreement is reached with the creditors to pay them in installments under someone else's name?

The heirs must pay off the deceased's debt before dividing the inheritance and should hasten to do so, because the soul of a believer is tied to their debt until it is paid off. There is no difference between debts in the name of the deceased or in the name of their institution, as all debts become due upon the death of the debtor. If a person takes responsibility for the debt or the heirs agree to pay it, this does not free the deceased until the debt is actually paid; for the Prophet, peace and blessings be upon him, said: "Now his skin has become cool." If the deceased had wealth, the debt must be paid from his wealth before it is divided among the heirs.
