It is not permissible to open an account in a usurious bank except out of necessity or a closely related need, provided that there is no Islamic alternative. For the use of covered cards to be permissible, sharia-compliant regulations must be met.

Accordingly, it is not permissible to acquire these gifts or benefit from them.
