Islamic law addresses financial ethics by:

1. **Prohibiting riba (interest)**: Ensures fairness in financial transactions and avoids exploitation.
2. **Avoiding gharar (excessive uncertainty)**: Promotes transparency and clarity in contracts.
3. **Encouraging ethical business practices**: Emphasizes honesty, integrity, and fairness in transactions.
4. **Mandating zakat (charitable giving)**: Promotes wealth distribution and supports social welfare.
