Is all of the money that a father sends from France via usurious banks, which is then deposited in usurious banks in Algeria, considered unlawful?

Riba (usury/interest) is forbidden by Islamic law, and one must avoid it. It is impermissible to partake of the father's money if it is known to be from forbidden usurious gains, except in cases of extreme necessity and only to the extent of that necessity. However, if the money was acquired through lawful means, it does not become forbidden merely by being deposited or transferred through usurious banks, and it is permissible to benefit from it.
