He wants to bring in a person to take his place in a ribaa-based investment bank account to save himself
Question

                A British Muslim brother started a ribaa-based investment account with the
      bank. The bank made it a condition that he should leave his deposit there
      for four years and not withdraw anything, then they will give him the
      interest earned each year. When he learned of the ruling (on ribaa), he
      wanted to withdraw the money from the bank, but the bank wants to charge a
      penalty for withdrawing the money ahead of time. If he brings in another
      person to take his place, the bank will not penalize this other person The
      question is: is it permissible for him, in order to be able to withdraw
      his money without being penalized, to bring in a kaafir to take his place
      so that he can withdraw his money, or not?
Praise be to Allah.We put this
      question to Shaykh Muhammad ibn Saalih al-‘Uthaymeen, may Allaah
      preserve him, who answered as follows:
 This is
      not permissible because it involves helping another to commit sin and
      transgression.
 And
      Allaah knows best.
