O You who have chosen to be graced with belief! Consume not one another's wealth wrongfully, not even in mutually agreed trade. Be just in your trade and cause not people to suffer losses. Do not destroy one another, and thus do not destroy your "Self". Allah is Merciful to you so you must be merciful to others." ("Illa" here means 'not even' and not 'except'). (2:188), (26:181).
