What is the ruling on the surplus money remaining after selling a house and settling the usurious bank installments, and is it permissible to give this money as charity to relatives, and what is the ruling on the money spent on renting a house during the past two years?

The obligation is to repent to Allah Almighty from the usurious transaction by feeling remorse, seeking forgiveness, and resolving not to return to it. It is not necessary to sell the house or donate its rent, because the prohibition of the loan pertains to the liability of the borrower. It is permissible to utilize the house or rent it out and donate its rent. The validity of repentance does not require selling the item purchased with a usurious loan.
