Is it permissible to deposit a check for 1000 dinars into an interest-bearing account to withdraw the full amount, knowing that depositing it into an Islamic account would incur a deduction of one dinar?

It is not permissible to pay check deposit fees from usurious interest. Rather, this interest must be disposed of by giving it to the poor and needy, and it is not permissible to benefit from it personally. Likewise, it is not permissible to open an account in a usurious bank except out of a recognized necessity, and one must limit oneself to a current account that does not accrue interest.
