What is the amount of money earned from gambling and converted to another currency whose value has increased, that must be spent: is it the original amount or its current value?

The amount of unlawfully acquired money must be disposed of in the same currency in which it was obtained. Any additional amount resulting from currency conversion is considered a profit derived from unlawful money, and there is a difference of opinion among scholars regarding this. Some scholars are of the view that whoever acquired unlawful money with the consent of the payer, then repented and desisted, may keep what has passed, and is not required to dispose of it at all.
