Islamic banks are open to both Muslims and non-Muslims. Islamic banking, as a system, adheres to Shariah principles and Islamic economics. Central to Islamic law is the prohibition of usury, known as Riba, which encompasses the collection and payment of interest. Moreover, Islamic law prohibits investment in activities deemed unlawful, or Haraam, such as those involving alcohol, pork, or media promoting gossip or pornography, contrary to Islamic values.The foundational principle of Islamic banking is the sharing of profit and loss, coupled with the prohibition of Riba. Key concepts in Islamic banking include profit sharing (Mudharabah), safekeeping (Wadi’ah), joint ventures (Musharakah), cost-plus pricing (Murabahah), and leasing (Ijarah).
