Riba is an Arabic term that refers to the concept of usury or interest in financial transactions. In Islamic finance, it is considered prohibited because it is seen as exploitative and unjust. Instead of earning money through interest, Islamic finance encourages profit-sharing and risk-sharing arrangements, which promote fairness and equity in economic dealings. The prohibition of Riba is rooted in Islamic teachings, particularly in the Quran and the Hadith. These texts emphasize ethical financial practices and the importance of supporting community welfare. By avoiding Riba, Muslims aim to foster a more equitable economic system that benefits all parties involved.
