What Is Riba? Why Islam Bans Interest, and Why It Matters Now

Frequently Asked Questions

What is riba in simple terms?

Riba is any guaranteed, predetermined increase charged for the use of money or for exchanging the same commodity in unequal amounts. In plain terms, it is interest: earning more money simply for lending money, with no shared risk and nothing produced. Islam treats that increase as unjust because the lender takes a return while carrying none of the borrower's risk.

Is all bank interest considered riba?

In the mainstream view of Islamic scholars, yes. Conventional loan and savings interest is riba because it is a fixed, guaranteed return on money itself, regardless of whether the underlying venture succeeds or fails. A small minority have argued modern banking interest is different, but the dominant position of bodies like AAOIFI and the major fiqh academies is that it falls under the prohibition.

What are the two types of riba?

Riba al-nasia is the riba of delay: the extra amount charged for lending money over time, which is what we call interest today. Riba al-fadl is the riba of excess: swapping the same commodity in unequal quantities, for example trading one measure of gold for a larger measure of gold. Both are prohibited, though riba al-nasia is the one that dominates modern finance.

Why does Islam prohibit riba?

Because it separates reward from risk. In riba the lender is guaranteed a return whether the borrower prospers or is ruined, which concentrates wealth upward and pushes risk downward onto the person who can least afford it. Islam permits profit, trade, and investment, but requires that anyone earning a return also share in the real risk and the real outcome.

What is the alternative to interest in Islamic finance?

Profit-and-loss sharing. Instead of lending at interest, capital takes an equity stake and shares in both the profit and the loss of the venture (musharaka and mudaraba). If the business fails, the financier loses alongside the entrepreneur. Venture capital in the West runs on this same risk-sharing logic, just without the ethical guardrails.

Is riba only a religious concept, or does it have real economic effects?

It has real effects. An interest-based system requires debt to grow faster than the money supply, which builds in recurring crises and a structural transfer of wealth from workers to asset-holders. That is why the prohibition on riba is not only a moral rule but an economic argument, one the modern debt system keeps proving.
