What is the ruling of Islamic law regarding what transpired in the customary session, specifically the valuation of part of the inheritance at its price at the time of the session and its division as inheritance, with the deduction of amounts previously sent?

If a portion of the inheritance is sold with the consent of the heirs and its price is taken without agreement, then the price is a debt upon the one who took it. The customary valuation of the sold portion is incorrect because it leads to an increase in the debt, which is usury (riba). The correct approach is to calculate the amount of money sent and deduct it from the debt, then each person pays back what they took. It is necessary to annul what was done in the customary session, and each individual must repay what they took. Whoever voluntarily pays more, it is better for them. However, if the value of the borrowed currency decreases, reconciliation is necessary, and compensation for its decrease should be made by looking at what it was equivalent to in a stable commodity, and the debtor and creditor should share the compensation. The division of the inheritance should be expedited.
