The practical conditions begin with three important tests. First, the company's main business itself must be lawful. Shares of conventional interest-based financial institutions or businesses centered on prohibited products and services are excluded.
Second, if an otherwise halal company still uses interest-based borrowing or deposits, the shareholder should express disapproval, preferably through the company's formal governance process. Third, any identifiable proportion of interest income included in dividends must be removed and given to charity rather than kept for personal benefit.
