Islamic finance is not a brand of investment product; it is the application of Islamic ethics to how money is earned, lent, spent, and given away. At its core are a handful of principles: wealth is a trust from Allah rather than an end in itself, transactions must be free of exploitation and excessive uncertainty, and profit should be tied to real economic activity and shared risk rather than a guaranteed charge on a loan.

This guide introduces those principles at a general, educational level: the prohibition of riba (interest/usury), fair dealing in trade, the obligations of zakah and voluntary sadaqah, and the basic concept of takaful (cooperative insurance). It intentionally does not screen funds, list stocks or ETFs, or recommend any specific product or provider.

Modern financial products (mortgages, credit cards, insurance policies, retirement accounts, and more) are structured in many different ways, and rulings on them can depend on the exact contract terms and your jurisdiction. This guide gives you the underlying principles; for a ruling on your specific situation, speak with a qualified, certified Islamic finance scholar or institution.
