If someone's wealth is unlawful, is it permissible for another to dispose of it on their behalf, whether or not they inform them, and should they pay the original million of unlawful money, or the two million if the owner of the unlawful money earned another million from the original million through lawful means?

It is permissible to dispose of ill-gotten gains on behalf of their owner. It is not necessary for the money to be in cash; some forms of wealth can substitute for others. The owner must be informed so that the gift is legally established for him and he may authorize the代理, and so that he may be rewarded for his intention to rid himself of the unlawful gain, and to prevent the money from being disposed of again. There is a disagreement regarding the amount to be disbursed if illicit funds are mixed with lawful funds and profit is made from them.
