Riba (Usury/Interest)

Riba is among the most severely prohibited matters in the entire Quran. Allah Most High declares war against those who deal in riba: "O you who believe, fear Allah and give up what remains of riba, if you should be believers. And if you do not, then be informed of a war from Allah and His Messenger” (al-Baqarah 2:278–279). The Prophet, peace be upon him, cursed the one who consumes riba, the one who pays it, the one who writes the contract, and the two witnesses to it, saying they are all equal in sin (Muslim). Ibn Abbas reported that the Prophet said that riba has seventy-three levels of sin, the lowest of which is equivalent to a man marrying his own mother.

Definition of Riba: Riba literally means increase or addition. In Islamic law, it refers to two types: Riba al-Nasi'ah (riba of delay/deferment) and Riba al-Fadl (riba of excess in exchange). Both are completely prohibited.

Riba al-Nasi'ah: This is the most commonly understood form — lending money with the condition of an additional amount being returned. This is what was practiced in pre-Islamic Arabia: a creditor would lend money and, upon the due date, would either receive repayment or double the debt. Any predetermined increase on a loan of money is riba al-nasi'ah, regardless of how small the rate. This includes all conventional interest-bearing loans and bank accounts that pay interest.

Riba al-Fadl: This type involves the exchange of ribawi commodities of the same type in unequal amounts. The Prophet, peace be upon him, specified six ribawi commodities: gold, silver, wheat, barley, dates, and salt. The rule for these commodities is: if exchanged for the same type, they must be equal in quantity and exchanged on the spot (hand to hand). If exchanged for a different ribawi type, they may be unequal but must still be exchanged on the spot. This rule prevents manipulation and hidden riba.

Contemporary Applications: All conventional bank interest — whether on loans, mortgages, savings accounts, or credit cards — constitutes riba al-nasi'ah and is categorically forbidden. Islamic finance products attempt to replicate the economic functions of these instruments through Shariah-compliant structures: murabahah (cost-plus sale), ijarah (lease), musharakah (partnership), and mudarabah (profit-sharing). Scholars debate the authenticity of some contemporary Islamic finance structures, and the student of knowledge should consult reliable scholars before entering complex financial arrangements.

Necessity and Riba: Some scholars permit engaging in riba-based transactions under extreme necessity (darura), such as taking a mortgage in a non-Muslim country where no Islamic alternative exists and renting is genuinely impossible. This view is held by some contemporary scholars but is not the dominant position. The majority counsel patience, rental accommodation, and seeking Islamic financial alternatives wherever possible.
