אם הרויח אדם פשוט בעולה שהטעהו לבו ולא מרצונו אותו פשוט לא יערב עם מעותיו פן יספה הצדיק עם הרשע: If a simple person unintentionally made profit in a prohibited way because he got deluded by his heart (without intent) - he shouldn't mix it with his (other) money as is stated "Will you even destroy the righteous with the wicked?"
