In the modern world of trade and finance, there exists a specific set of rules that makes it much easier and simpler to maintain transparency and fairness. For example, in Islamic finance, one of the important rules is the prohibition of riba (usury, charging interest) – this is profit obtained without labor, risk, or real economic activity. This overview will help you understand what ribawi items are and why this prohibition applies to them.
What is Riba: Introduction to the Concept
The literal translation of the word “riba” means excess, unlawful profit. In Islamic economics, this word refers to interest or unfair profit obtained as a result of deferred payments or as a result of unequal (dishonest) exchange of identical goods.
Thus, it is forbidden to simply “earn money” without creating any real value.
Islamic scholars have identified 6 items whose exchange is subject to special rules:
- Grain (this list also includes wheat and barley).
- Raisins (or grapes).
- Salt.
- Dates.
- Gold.
- Silver.
The choice of these particular items was not made by chance. After all, historically this set of products and goods was considered one of the most important and valuable. Therefore, fair exchange was regulated using their example.
History of the Prohibition
When Islam gradually spread throughout the world, the Prophet introduced rules of fair exchange, according to which it was forbidden to make profit from delay or increasing the quantity of the same item. Equal exchange or trade in different types of goods was permitted.
Thus, riba became a moral and economic instrument. The main purpose was as follows:
- It was necessary to protect the poor and vulnerable segments of the population.
- It was necessary to encourage honest labor and popularize real transactions with goods.
- It was necessary to prevent the abuse of credit and large amounts of debt.
There is even a hadith in which the Prophet said: “Gold for gold, silver for silver, wheat for wheat, barley for barley… equal for equal, and delay is forbidden.” This is how special Islamic rules for fair and transparent exchange emerged.
How Does It Work in Practice?

In practice, a simple and clear rule applies: if one of the items included in the above list is exchanged for the same item, this exchange must be equal and immediate.
To understand how the rule “works” in practice, it is enough to review several relevant examples:
- Exchanging 1 kg of wheat for 1 kg of wheat immediately – everything is in order and within the rules.
- Exchanging 1 kg of wheat for 2 kg of wheat with delay – this is considered riba.
- Exchanging wheat for milk/apples – these are completely different categories and types of goods, which means the prohibition does not apply.
As a result, Islamic law helps stimulate honest transactions, where profit is obtained only through real exchange, and not simply through delay or increase in amount.
If you need to quickly check whether a specific transaction is riba, you need to ask several leading questions:
- Do you need to exchange one item for exactly the same item?
- Does the exchange occur with delay or in different quantities?
If the answer to both questions is “yes,” then it is riba. If there is an exchange of different goods or identical goods with equal instant value, then everything is legal and fair.
Why These 6 Items Specifically?
The choice of these items was not made by chance. For example, dates, salt, grain, and raisins are called basic food products that were vital to people at that time.
As for gold and silver – these were money on which interest could be charged. As a result, the following concept applied: if dishonest transactions were made on vital things and products, such a decision could lead to social injustice.
However, riba is not only about money. Many hold the mistaken opinion that the prohibition of riba concerns only bank interest. This prohibition concerns real goods and real exchange of them. Even in ancient markets, people carefully monitored the process of exchanging salt, grain, or gold so that everything happened fairly. Therefore, the popular idea today of “don’t get rich simply on the difference in quantity” existed much earlier than modern credits and interest appeared.
Different Types of Riba
Two main types of riba are known, each of which has certain differences:
- Riba an–Nasi’ah – this is profit obtained from deferred payment (like interest on a loan).
- Riba al–Fadl – this is unequal exchange of one item for exactly the same one (for example, 1 kg of wheat for 2 kg of wheat).
Thus, it matters not only what exactly is being exchanged, but also how exactly the exchange process occurs.

How Is This Applied Today?
In the modern world, direct exchange of salt, wheat, or other goods is practically no longer used anywhere. Despite this, the principles of ribawi are actively used in Islamic banks and investments.
For example, instead of interest, banks make profit through trade, investments, or through joint ventures. This approach helps stimulate the launch and development of real economic projects, and not just earn money on debts.
Why Are These Rules and Prohibitions Important?
Despite the fact that in the modern world most transactions occur with money and credit, the idea of ribawi reminds all people about fairness and transparency.
Thanks to this idea, it is possible to:
- Prevent unfair exploitation of weaker market participants.
- Form trusting relationships between people, full–fledged companies and enterprises.
- Motivate real trade and production of popular goods.
Ribawi items are not just ancient archaism, but a practical rule of fair exchange that can be applied today. All 6 items remind modern people that real value is created through labor, honest transactions, and certain risk, and not only through allocated time or increasing the amount of money.
