2.3 Gharar, Maysir & Prohibited Activities

Key Takeaways

  • Gharar denotes excessive ambiguity, uncertainty, or lack of critical information regarding the essential elements of a contract, such as price, existence, deliverability, or subject matter.

  • Gharar Fahish (major uncertainty) invalidates commutative commercial contracts ('Uqud al-Mu'awadat), whereas Gharar Yasir (minor, unavoidable uncertainty) is legally tolerated to prevent severe market hardship.

  • Maysir (gambling) and Qimar (wagering) are zero-sum allocations of wealth based on pure chance, fundamentally distinct from legitimate commercial risk-taking (Mukhatarah / Ghurm) anchored in asset ownership and value creation.

  • Conventional insurance, naked short-selling, and speculative binary derivatives are impermissible because they embody excessive Gharar and synthetic gambling characteristics.

  • Islamic commercial law strictly prohibits commercial dealing in non-halal activities (alcohol, pork, gaming, usurious banking), and capital market regulators enforce rigorous quantitative and qualitative screening benchmarks.

Gharar, Maysir & Prohibited Activities

Quick Summary: Islamic commercial jurisprudence establishes market integrity through transparency, ethical accountability, and mutual consent. The framework strictly prohibits Gharar (deceptive ambiguity or contract hazard), Maysir / Qimar (gambling and zero-sum wagering), and commercial engagement in unlawful (Haram) industries such as usurious finance, alcohol, gaming, and swine production.


1. Definition and Legal Nature of Gharar

Linguistically, Gharar derives from the Arabic root ghurra, denoting peril, deceit, risk, hazard, delusion, or exposure to loss. In Islamic jurisprudence (Fiqh), Gharar refers to excessive ambiguity, uncertainty, or lack of knowledge regarding the fundamental terms, pricing, quality, existence, or deliverability of the subject matter in an exchange contract.

Scriptural Foundation

The fundamental prohibition of Gharar is established in multiple authentic Prophetic traditions, most prominently the Hadith narrated by Abu Hurairah (Sahih Muslim):

"The Messenger of Allah (peace be upon him) prohibited sales by the throwing of stones (Bai' al-Hasah) and sales involving Gharar (Bai' al-Gharar)."

In pre-Islamic Arabia, Bai' al-Hasah involved a buyer throwing a pebble at an array of garments, with the contract binding upon whichever item the stone struck, regardless of its quality, size, or price. Shariah outlawed this and all analogous mechanisms because they supplant deliberate mutual consent with blind hazard.

The Legal Harm of Gharar

Gharar is prohibited because it fosters information asymmetry, allows one party to unjustifiably exploit the ignorance of another, and inevitably leads to post-contractual disputes, friction, and animosity (Niza' and Adawah) between market participants.


2. Classification: Gharar Fahish vs. Gharar Yasir

Islamic law recognizes that complete, omniscient certainty in human affairs is impossible. Therefore, classical jurists categorized Gharar according to its magnitude and commercial impact:

                               GHARAR CLASSIFICATION
                 ┌───────────────────────┴───────────────────────┐

      • Renders exchange contracts void               • Fully tolerated by Shariah
      • Dominates the contract                        • Unavoidable in normal commerce
      • Strikes core subject matter                   • Ancillary / negligible impact
      • No overriding public necessity                • Covered by public need (Hajah)

The Four Conditions of Prohibitive Gharar (Gharar Fahish)

According to classical jurists (such as the Maliki scholar Al-Baji and contemporary codifications by AAOIFI and BNM SAC), Gharar invalidates a commercial contract only when all four of the following conditions are simultaneously met:

  1. The Gharar is excessive in degree (Kabir / Fahish): The uncertainty must be substantial enough that reasonable market actors would deem the contract an unacceptable hazard or gamble.
  2. The contract is a commutative commercial exchange ('Aqd Mu'awadah Maliyyah): Gharar Fahish invalidates bilateral sales, leases, and partnerships. Conversely, it is tolerated in gratuitous / charitable contracts ('Uqud al-Tabarru'at), such as gifts (Hibah), bequests (Wasiyyah), and endowments (Waqf). A donor may gift "whatever fruit this orchard produces this season" because the recipient incurs no financial outlay and cannot be defrauded.
  3. Absence of overriding public necessity ('Adam al-Hajah al-Māssah / Darurah): If an economic arrangement involves minor ambiguity but is vital for human welfare and cannot be practically concluded without it, public necessity (Hajah) takes precedence.
  4. The Gharar affects the principal subject matter (Asl al-'Aqd): The uncertainty must strike the core asset or primary deliverable of the contract. If the uncertainty is merely ancillary or subsidiary (Tabi'), the contract remains valid under the legal maxim: "Yuthbatu tab'an ma la yuthbatu aslan" (What is tolerated as a subsidiary element is not tolerated as a primary element).

Classical Illustrations of Gharar Fahish

  • Selling the unborn fetus of a camel (Habal al-habala): The contract is void because the existence, health, gender, and live birth of the fetus are completely uncertain.
  • Selling fish in open water (Samak fi al-ma'): Selling fish swimming freely in the ocean or an uncontained river before capture, because delivery is not within the seller's power ('Adam Maqdur al-Taslim).
  • Selling birds in the sky (Tayr fi al-hawa'): Selling wild birds before they are trapped.
  • Selling fruit before it ripens (Bai' al-thimar qabla buduwwi salahiha): Selling agricultural produce before it is safe from blight and exhibits clear signs of maturity.
  • Selling a runaway animal (Al-jamal al-sharid): Transferring ownership of an escaped animal whose recovery is doubtful.

Gharar Yasir (Minor, Tolerable Uncertainty)

Gharar Yasir refers to minimal, trivial, or customary ambiguity that reasonable people routinely absorb without litigation. Examples include:

  • Purchasing an existing home without excavating the foundation to examine the underground plumbing and rebar.
  • Paying a fixed monthly water or electrical utility fee where exact consumption fluctuates slightly.
  • Hiring a vehicle or hotel room where wear-and-tear varies based on normal human usage.

3. Gharar in Contemporary Financial Instruments

Modern financial engineering contains numerous instruments that run afoul of the prohibition of Gharar Fahish:

A. Conventional Insurance

Conventional commercial insurance is impermissible in Islamic jurisprudence because it embodies all four conditions of Gharar Fahish:

  • Uncertainty of Occurrence: The policyholder does not know if an insurable event will ever take place.
  • Uncertainty of Timing: If the calamity occurs, the timing is completely unknown.
  • Uncertainty of Magnitude: The policyholder cannot know how much compensation they will receive relative to the cumulative premiums paid.
  • Exchange Contract Context: Conventional insurance is structured as an exchange contract (Mu'awadah)—premiums exchanged for financial compensation—meaning Gharar invalidates it. Islamic finance resolves this through Takaful, which restructures the relationship as mutual assistance (Ta'awun) financed via charitable contributions (Tabarru').

B. Naked Short-Selling

In naked short-selling, an investor sells shares that they neither own, possess, nor have borrowed at the time of the sale, intending to buy them back later at a lower price. This directly breaches the explicit Prophetic injunction: "La tabi' ma laysa 'indak" (Do not sell what you do not own/possess). The practice injects acute settlement risk, speculative market manipulation, and contractual non-deliverability.

C. Speculative Derivatives (Options, Futures & CDS)

Conventional derivative contracts such as binary options, unhedged call/put options, and synthetic credit default swaps (CDS) involve pure zero-sum bets on directional price movements. In most conventional option contracts, neither party intends to take physical delivery of the underlying asset; the contract is cash-settled based on synthetic price variance. This incorporates Gharar Fahish and borders directly on speculative wagering.


4. Prohibition of Maysir (Gambling) and Qimar (Wagering)

Islamic law treats Maysir and Qimar as severe transgressions against economic ethics, condemning them in the Holy Quran alongside intoxicants:

"O you who have believed, indeed, intoxicants, gambling [maysir], [sacrificing on] stone alters [to other than Allah], and divining arrows are but defilement from the work of Satan, so avoid it that you may be successful." (Surah Al-Ma'idah, 5:90)

Legal Definitions

  • Maysir: Any scheme, activity, or transaction where money or value is placed at risk and wealth is acquired effortlessly (kasb bila 'amal) based purely on luck, chance, or conjecture, rather than productive economic endeavor.
  • Qimar: A specific competitive game of chance or wager between two or more parties where the gain of one party is entirely contingent upon and directly matched by the loss of the counterparty. One emerges as an absolute winner while the other suffers an uncompensated total loss.

Distinguishing Commercial Risk from Speculative Gambling

A critical competency for the IBFIM AQIF examination is distinguishing lawful entrepreneurial risk from prohibited gambling:

                   LEGITIMATE RISK vs. ILLICIT GAMBLING
┌───────────────────────────────┬───────────────────────────────┬───────────────────────────────┐

│                               │ Al-Kharaj bi al-Daman         │ under Surah Al-Ma'idah 5:90   │
├───────────────────────────────┼───────────────────────────────┼───────────────────────────────┤
│ Outcome Structure             │ Non-zero-sum; both parties    │ Zero-sum; one party wins      │
│                               │ can mutually prosper          │ entirely at the other's loss  │
└───────────────────────────────┴───────────────────────────────┴───────────────────────────────┘

Under the legal maxims "Al-Ghurm bi al-Ghunm" (Gain is accompanied by risk) and "Al-Kharaj bi al-Daman" (Entitlement to yield corresponds to liability for loss), Shariah actively encourages calculated, productive commercial risk-taking (Mukhatarah or Ghurm). Legitimate commercial risk creates factories, distributes goods, and finances enterprises. Conversely, Qimar manufactures an artificial hazard solely for wealth redistribution.


5. Prohibited Goods, Non-Halal Activities & Shariah Screening

In addition to procedural contract defects like Riba and Gharar, Islamic commercial law prohibits transactions whose subject matter consists of inherently unlawful goods or services (A'yan Muharramah):

Core Prohibited Sectors

  1. Intoxicants & Alcohol (Khamr): Manufacturing, distributing, wholesaling, retailing, or promoting alcoholic beverages.
  2. Swine / Porcine Products: Rearing, slaughtering, processing, or selling pork and swine-derived gelatin or enzymes.
  3. Non-Halal Food & Carrion (Maytah): Animals slaughtered without invoking Allah's name or slaughtered contrary to Islamic Shariah requirements.
  4. Conventional Financial Services: Commercial banking, conventional insurance, moneylending, and usurious debt brokering.
  5. Gambling & Gaming: Operating casinos, lotteries, betting parlors, and gaming software.
  6. Adult Entertainment & Prostitution: Pornography, sexually explicit media, and escort services.
  7. Tobacco & Dangerous Substances: Products causing verifiable severe harm to human life and health. Tobacco, cigarettes and e-cigarettes appear on the Securities Commission Malaysia's list of non-compliant activities.

Many international ethical and Shariah screens also exclude weapons and defence manufacturers. That exclusion depends on the screen, not on a universal fiqh rule, and the SC's list does not name arms.

Shariah Equity Screening Benchmarks (Securities Commission Malaysia)

In modern Islamic capital markets, Shariah-compliant funds may invest only in listed companies that pass a Shariah screen. The Shariah Advisory Council of the Securities Commission Malaysia (SAC SC) classifies Bursa Malaysia securities using a two-tier quantitative approach: a single business activity benchmark plus two financial ratio benchmarks. It also applies a qualitative check on the public perception of the company's activities from the perspective of Islamic teaching. The SC publishes the list of Shariah-compliant securities twice a year, in May and November.

Tier 1: The Single 5% Business Activity Benchmark

At its 288th meeting (24 February 2025) and 296th meeting (13 November 2025), the SAC SC resolved to introduce a single business activity benchmark of 5% and to remove the former 20% benchmark. The single benchmark applies to listed companies with financial years ending on or after 31 December 2025. The contribution of all non-compliant activities is measured against the Group total income (revenue, other income and share of profit). Earlier revisions had already dropped profit before tax as a separate test. The activities counted include:

  • conventional banking and lending, and conventional insurance;
  • gambling, liquor, and pork, plus their related activities;
  • non-halal food and beverages, including food products without halal certification;
  • tobacco, cigarettes, and e-cigarettes;
  • interest income from conventional accounts and instruments, and dividends from non-compliant investments;
  • Shariah non-compliant entertainment, and cinema;
  • share trading, stockbroking, and rental received from non-compliant activities.

Note

Older textbooks describe two business activity benchmarks: 5% for clearly prohibited activities and 20% for mixed activities such as hotels, share trading and non-compliant rental. That two-benchmark design dates from the 2013 revision. Know both: the SC now applies one 5% benchmark.

Tier 2: Financial Ratio Benchmarks (33% Rules)

These two ratios measure riba-based elements in a company's statement of financial position. Each must be less than 33%:

  1. Cash over Total Assets: only cash placed in conventional accounts and instruments counts; cash in Islamic accounts is excluded.
  2. Debt over Total Assets: only interest-bearing debt counts; Islamic financing and sukuk are excluded.

Section 11.2 compares this methodology with international index screens and explains dividend purification.

Test Your Knowledge

A wealthy philanthropist promises to gift his entire unharvested fruit crop to a local orphanage next season, regardless of whether the harvest yields 100 kilograms or 1,000 kilograms. Under Islamic commercial law, why is this contract legally valid despite containing major uncertainty regarding the quantity and deliverability of the fruit?

A

Because fruit is a non-ribawi agricultural commodity exempt from all uncertainty rules.

B

Because the donor included an express cooling-off option (Khiyar al-Shart) in the gift contract, which removes all gharar.

C

Because the contract was approved by a registered municipal commodities exchange.

D

Because Gharar Fahish is legally tolerated in gratuitous, charitable contracts ('Uqud al-Tabarru'at).

Test Your Knowledge

Which of the following scenarios constitutes illicit Qimar (wagering) rather than legitimate Shariah-compliant commercial risk-taking (Mukhatarah)?

A

An entrepreneur invests RM50,000 in inventory for a retail shop, absorbing the risk that market prices may drop before sales occur.

B

Two traders agree that A pays B RM5,000 if a stock index rises and B pays A RM5,000 if it falls, without owning any shares.

C

A farmer enters an agricultural Salam contract agreeing to deliver 5 metric tons of grade-A wheat at an agreed price after six months.

D

An Islamic bank purchases an industrial machine for RM200,000 and leases it to a corporate client under an Ijarah contract, assuming asset ownership risk.

Test Your Knowledge

Under the Shariah screening methodology now applied by the Shariah Advisory Council of the Securities Commission Malaysia (SAC SC), what threshold applies to income from conventional banking or gambling operations at a listed company?

A

Zero tolerance: any income at all from these activities automatically disqualifies the company

B

Less than 33% of the company's total assets, the same test used for conventional debt

C

Less than 5% of the group's total income, under the single business activity benchmark now in force

D

Less than 20% of group revenue or profit before tax, because banking is a mixed activity
