Is it permissible to deposit money in the National Savings Fund in Morocco and then donate the interest to the poor, in order to protect the money from loss, given that the depositor was unaware of the existence of interest at the time of deposit?

The ruling on depositing money in a savings fund has been previously established. If the fund offers usurious interest, then it is not permissible to deposit money in it, as this constitutes aiding in usury and assenting to it. However, if a person is compelled to deposit money, then they must dispose of the usurious interest by giving it away in charity or using it for general Muslim welfare, and it is not permissible to personally benefit from it.
