The principles of Islamic finance

Shariah and fiqh as the foundation

Islamic law has two layers. The shariah is divine law, based on the Qur'an and the sunnah. The fiqh consists of the legal rules that shariah scholars have derived from those sources. Within the fiqh, financial principles are developed that give direction to permitted transactions.

An important starting point is that everything is in principle permitted unless an explicit prohibition applies. This means financial innovation is possible, so long as the core principles of Islamic finance are respected.

The prohibition on interest (riba)

The best known principle is the prohibition on interest. Interest is seen as a form of unjustified enrichment, because one party receives a fixed return without carrying real risk. Within Islamic finance, money may not be a business model in its own right. A return is permitted only where entrepreneurial risk or real economic activity stands behind it.

In concrete terms this means loans bearing interest are not permitted. Instead, the structures used are ones in which profit, loss and risk are shared, or in which transactions are tied to tangible assets.

Risk sharing rather than risk transfer

A core principle of Islamic finance is risk sharing. The parties share both the upside and the downside of a transaction. This runs against conventional financing, where risk is often placed entirely with the customer while the financier receives a fixed return.

In Islamic finance every party must have genuine economic involvement. That produces more balance and prevents excessive debt burdens.

The prohibition on excessive uncertainty (gharar)

Contracts may not contain excessive uncertainty. Every essential element of an agreement must be clear in advance: price, term, and the rights and obligations of the parties.

This principle promotes transparency and prevents speculative or unfair arrangements. Financial products must be comprehensible and based on clear terms.

The prohibition on speculation and gambling (maysir)

Transactions based primarily on chance, gambling or extreme speculation are not permitted. This excludes many high-risk financial products, such as pure derivatives trading with no underlying economic value. Islamic finance is directed at real value creation rather than profit from price movements.

A link to real assets

Financial transactions must be connected to tangible assets or concrete economic activity. Money does not flow loose through the system but is always tied to property, trade or services. This makes Islamic finance intrinsically more stable and better anchored in the real economy.

Ethical and social responsibility

Alongside legal rules, ethics play a central part. Investment in sectors considered harmful, such as alcohol, gambling or weapons, is not permitted. Financial decisions should contribute to social justice and sustainability.

In summary

Islamic finance turns on fairness, transparency and risk sharing. The system prevents one party from taking a structural advantage without carrying responsibility, and encourages forms of financing tied to real value and shared interest.
