Islamic finance is rooted in the principle that investments should create social value and not merely wealth. The Quran, the 1,400-year-old text that governs followers of Islam, prohibits riba, the charging or receiving of monetary benefit from lending money, interpreted in modern terms as a prohibition against interest. Islamic finance also prohibits excess risk or uncertainty (gharar), gambling (maysir), and sinful activities (haram). Transactions generally must be tied to real, tangible assets.
