Two Questions and Two Answers

Is it allowed?

There is no objection: perfume, although foreign,
is bound to be permissible. You can take half of it,
mix with interest and deposit in a bank.

Any restriction?

It is ok if it is forbidden; give the other half
to her dead brothers so that it comes under their feet.
Using medicine is all that is left.
