Questions on the Explanation of the Book of Nullifiers of Islam

Question:
What is the ruling on placing money in riba (usury or interest) banks? Is it a deposit or is it a loan? One of the honorable scholars told us that it is a loan, because the conditions and regulations of a loan apply to it, not those of a deposit.

Answer:
No, you did not bring it to be treated as a loan; you brought it for safekeeping only, as a deposit for preservation, and they dealt with it. It is supposed that the trust was not dealt with. This is a deposit and a trust. It is supposed that they do not deal with it except with your permission, and you did not give them permission to deal with it, so their dealing with it is not permissible. Yes, it is a deposit and a trust, and the trust is preserved until its owner asks for it, without the one holding the deposit dealing with it.
