It is permissible to deposit money with national banks, in other words loaning the banks?

Answer

This, however, must be done without making a provision for charging interest on the money deposited, meaning not stipulating that the banks should give an undertaking to pay the interest on the loan. The opposite of this is that the depositor reaches a conclusion that if the bank was not going to pay the interest, he would not demand it. The intent to demand the interest does not contradict the non-stipulation. Similarly, the intent not to demand the interest does not contradict stipulation. That is because each of which is alien to the other. Given that the bank is governmental, if he receives any interest, he should give half of the interest to faithful needy Shia Muslims and use the other half.
