Are the costs of transferring money derived from usury to be paid from the money itself, or from the sender's own money, and is it permissible to stop helping someone whose trustworthiness is doubted?

Repentance is obligatory for dealing with usury. It is not permissible to deposit money in usurious banks except in cases of extreme necessity, with the disposal of interest in charitable causes and for the general welfare of Muslims. When sending ill-gotten money to the poor, the transfer fee is the responsibility of the sender and should not be deducted from the money. It is necessary to verify the recipient and not send money to unknown individuals solely through the internet.
