Is it permissible to take interest from French banks where money is deposited, knowing that it is not possible to keep it in homes and that banks benefit from it by investing it?

If it is possible to place the money in a current account without interest, then do so. If it is not possible and you place it in a savings account, then do not benefit from it for yourself or your family. Rather, donate it to the poor among Muslims, because leaving it to entities that spend it on malicious purposes causes greater harm.
