Is it permissible to transfer a salary account to a nearby usurious bank for convenience, if all banks are usurious? And is there a natural remedy for beard growth?

Opening an account in usurious banks is forbidden, even without interest, because it involves cooperation in sin. However, if there is a need to open an account without interest, due to the absence of an Islamic bank or difficulty in accessing one, then there is no harm. As for treating beard growth, this is a matter for doctors, with the caveat that the command to let the beard grow does not imply that treating its growth is desirable.
