Is it permissible to deduct the total daily charity against the amount paid to lend to the brother and settle his usurious debts to ease the burden on his wife and children when selling the apartment? And is there sin incurred by settling usurious loans? And is it permissible to settle these debts from Zakat al-Mal? And what is the brother's condition now, and is it possible to atone for his sin, taking into account the usurious loans?

First: It is permissible for you to give the daily charity you collect to pay off your deceased brother's debt or to support his needy children; this is considered a donation from you.

Second: Paying off your brother's debt is permissible and is an act of righteousness towards him after his death, clearing his liability. However, it is not permissible to pay usurious interest unless the bank insists on it and there is no alternative but to pay it, while trying to have it waived.

Third: It is possible to pay off the deceased's debts, seek forgiveness for him, give charity on his behalf, and care for his family and be kind to his children.
