Question:

Someone has interest money, which he then gives to a poor person as a gift on condition that the person returns some to him as a gift. The poor person then accepts it and returns it to the original owner. Can the owner now use the money?

Answer:

This scheme to make the interest money halaal is not acceptable and will not be halaal for the person.

And Allah knows best!
