Islamic law addresses **financial ethics and responsibility** through the following principles:

1. **Prohibition of Riba (Interest):** Bans charging or paying interest to prevent exploitation and promote fair financial practices.

2. **Avoidance of Gharar (Excessive Uncertainty):** Prohibits excessive ambiguity in contracts, ensuring transparency and fairness in financial transactions.

3. **Promotion of Honest Trade:** Encourages truthful dealings, honesty, and trustworthiness in business, condemning fraud and deception.

4. **Zakat and Charity:** Mandates giving a portion of wealth to the needy (Zakat) and encourages voluntary charity (Sadaqah) to support social welfare and reduce economic inequality.

5. **Ethical Investment (Halal):** Requires investments in ethical, socially responsible, and Sharia-compliant ventures, avoiding haram industries like alcohol or gambling.

6. **Contracts and Fulfillment of Promises:** Stresses honoring contracts and fulfilling promises, ensuring accountability and trust in financial relationships.

Through these guidelines, Islamic law promotes a financial system rooted in ethics, responsibility, and social justice.
