Is selling the elderly parents’ house to free the sister from the predicament of usury more worthy than her remaining in usury, and do the siblings and parents bear the burden of sin for refusing to sell the house in this case?

Borrowing with interest is forbidden, as it is usury (riba) which has been prohibited by textual evidence, and those who practice it have been cursed. Whoever borrowed with usury and repented, must feel remorse and resolve not to return to it. They are not required to pay the interest if they can avoid it; otherwise, they must pay it. It is recommended to expedite the repayment of usurious installments to be free from the contract. No one bears the sin of another; the burden of sin falls on whoever participated in or assisted with the usurious contract. It is not necessary to sell a shared house for the sake of selling another person's share, especially if that does not increase the price of the owner's share.
