What is the ruling on money spent from usurious funds on expenses whose benefit has ceased, and what is the ruling on things purchased with these funds whose benefit is still ongoing, and what is the ruling on suggesting to a brother to obtain usurious interest, and what should one do who is unable to work or study due to illness while continuing to receive treatment, and what must he do to repent from purchasing non-essential items with usurious money in the past?

Firstly: It is not permissible to suggest depositing money in an interest-based bank, and the debtor must be advised to refrain from doing so.

Secondly: If you are poor and in need, there is no sin upon you in benefiting from illicit money if it reaches you, and it becomes lawful for you.

Thirdly: Continue to advise your brother to stop investing money in interest-based banks and to search for Islamic alternatives, as it is forbidden to deal with interest-based banks when an Islamic alternative exists.
