Islamic banking has expanded to over 70 countries since the mid-1970s and prohibits interest-based earnings and investments in activities deemed sinful by Sharia law like alcohol, tobacco, and gambling. India's current banking laws prohibit Islamic banking practices like profit-loss financing and buying/selling goods. However, experts argue that Islamic banking could mobilize large amounts of capital from devout Muslims and foreign investors in Middle Eastern and Southeast Asian countries, and new financial products from Islamic banking have the potential to be safer than existing ones. While regulating both Islamic and conventional banking poses challenges, Islamic banking could promote financial inclusion for India's large Muslim population and foreign investment from Islamic nations.
