Core Shariah Principles

Riba

The Arabic term for interest or usury. Riba refers to any guaranteed, predetermined increase on a loan or deposit — in practical terms, conventional interest as charged by banks. It is explicitly prohibited in the Quran and forms the foundational prohibition that drives the entire Islamic finance system. Both paying and receiving riba is prohibited.

Gharar

Excessive uncertainty or ambiguity in a financial contract. Gharar exists when the subject matter, price, or terms of a contract are unclear or contingent on uncertain events in a way that could lead to dispute or injustice. Conventional insurance and speculative derivatives typically contain elements of gharar.

Maysir

Gambling or speculation. Maysir refers to any transaction where wealth is acquired through chance rather than productive effort or genuine exchange. It is prohibited under Shariah. Excessive speculation in financial markets, gambling, and lottery-type instruments all fall under maysir.

Halal

Permissible under Islamic law. In a financial context, halal describes products, investments, and transactions that comply with Shariah principles — free from riba, gharar, maysir, and prohibited business activities.

Shariah

Islamic law, derived from the Quran, the Sunnah (practices and sayings of the Prophet Muhammad, peace be upon him), scholarly consensus (ijma’), and analogical reasoning (qiyas). In finance, Shariah compliance means structuring transactions within this legal framework.

Shariah Supervisory Board

A panel of qualified Islamic scholars who review and certify financial products, institutions, and funds to ensure they comply with Shariah principles. Any credible Islamic financial product should be certified by an independent Shariah supervisory board. They conduct ongoing audits and issue rulings on specific transactions.

Fatwa

A formal legal opinion issued by a qualified Islamic scholar (mufti) on a specific question of Islamic law. In Islamic finance, fatwas are issued to determine whether a specific product, structure, or transaction is permissible. Multiple scholars may issue different opinions on the same question.

Darura

Necessity. Under Islamic jurisprudence, genuine necessity can permit actions that would otherwise be prohibited — provided no permissible alternative is available. In Islamic finance, darura is sometimes invoked to justify the temporary use of conventional financial products when no Shariah-compliant alternative exists.

Islamic Banking and Finance Products

Murabaha

Cost-plus financing. The bank purchases an asset and sells it to the client at a marked-up price, payable in instalments. The profit margin is agreed upfront and fixed — the bank earns a return through the trade transaction, not through interest. Widely used for home financing, vehicle finance, and business asset purchases.

Musharakah

Partnership or joint venture. Two or more parties contribute capital to a business or investment, sharing profits according to an agreed ratio and losses proportionally to their capital contribution. Musharakah is one of the most authentically Islamic financing structures because profit and loss are genuinely shared.

Diminishing Musharakah

A variant of musharakah used for home financing. The bank and client jointly own an asset such as a property. The client progressively purchases the bank’s share over time while paying rent on the bank’s remaining portion. By the end of the term, the client owns the asset outright. This is the structure behind most halal home loans in South Africa. Read more: Halal Home Loans in South Africa.

Mudarabah

A profit-sharing arrangement between a capital provider (rab al-mal) and a fund manager or entrepreneur (mudarib). The capital provider provides funds; the mudarib provides expertise and management. Profits are shared according to an agreed ratio; losses are borne by the capital provider (unless the mudarib was negligent). Used in Islamic savings accounts, investment funds, and Takaful structures.

Ijarah

Leasing. The bank purchases an asset and leases it to the client for an agreed period, charging a rental fee. At the end of the lease, the asset may be returned, purchased outright, or transferred to the client through a separate agreement. Used for vehicle finance, equipment leasing, and property financing.

Wakala

Agency. A principal appoints an agent (wakeel) to carry out a financial activity on their behalf, for a fixed fee. Widely used in Takaful, where the Takaful operator acts as wakeel managing the participants’ fund, and in Islamic banking and investment management.

Istisna

A manufacturing or construction contract. One party commissions another to manufacture or construct a specific asset, with payment made progressively as the work is completed. Used for project finance, property development, and large-scale infrastructure.

Qard Hasan

A benevolent loan — given without any expectation of return beyond the principal amount. No interest, no profit margin, no fees. The borrower repays only what they borrowed. In Islamic banking, qard hasan structures are used for certain current accounts where no return is earned or paid on deposits.

Islamic Capital Markets

Sukuk

Often described as Islamic bonds, sukuk are certificates representing proportional ownership in an underlying asset or pool of assets. Returns are derived from the asset’s performance or rental income — not from interest payments. Unlike conventional bonds, sukuk holders are asset owners, not creditors. South Africa has issued sovereign sukuk; global sukuk markets are accessible to South African investors through certain fund structures.

Shariah-Compliant Equity

Shares in companies whose business activities and financial structure pass Shariah screening criteria. The company must not derive significant revenue from prohibited sectors (alcohol, tobacco, gambling, conventional banking, weapons) and must not carry excessive interest-bearing debt. Read more: How Shariah Screening Works.

Shariah Screening

The process of evaluating companies, funds, or investments against Shariah criteria. Involves two layers: business activity screening (what the company does) and financial ratio screening (how the balance sheet is structured). Read more: How Shariah Screening Works.

Purification

The process of removing non-compliant income from an investment portfolio or fund. Even Shariah-screened companies may generate small amounts of non-compliant income. The Shariah board calculates the proportion of income that is non-compliant, and investors donate that proportion to charity. Read more: Are Unit Trusts Halal in South Africa?

Takaful (Islamic Insurance)

Takaful

Islamic cooperative insurance. Participants contribute to a shared fund with the intention of mutual assistance (tabarru’). If any participant suffers a specified loss, they receive a payout from the collective fund. Any surplus after claims and expenses is returned to participants. Read more: Takaful in South Africa.

Tabarru’

Charitable donation or contribution. In Takaful, participants make tabarru’ contributions to the shared fund — structured as donations for mutual assistance rather than premium payments. This resolves the gharar concern in conventional insurance: the participant is donating to help others, not wagering for personal gain.

Family Takaful

Long-term Takaful covering life, disability, critical illness, and savings objectives — the Islamic equivalent of life insurance and endowment policies. Providers in South Africa include Old Mutual Albaraka and Takafol SA.

General Takaful

Short-term Takaful covering specific risks such as motor, property, commercial, and medical insurance. Structured on cooperative risk-sharing principles with Shariah-screened investments of the fund.

Surplus Distribution

In Takaful, when the participants’ fund generates more income than is paid out in claims and expenses, the surplus belongs to the participants — not the Takaful operator. This surplus is distributed back to participants, reducing the net cost of cover over time.

Zakah and Charitable Giving

Zakah

The obligatory annual wealth purification tax — one of the five pillars of Islam. Calculated at 2.5% of qualifying net wealth held above the nisab threshold for one full lunar year (hawl). Applies to cash, gold, silver, trade goods, investments, and certain other assets. Read more: Zakah in South Africa: The Complete Guide.

Nisab

The minimum wealth threshold above which the Zakah obligation applies. Typically calculated as the equivalent of 87.48 grams of gold or 612.36 grams of silver in local currency — whichever is lower in rand terms at the time of calculation.

Hawl

The lunar year cycle for Zakah. Zakah is calculated and paid annually on a specific date (your hawl date) — typically the date you first became nisab-eligible. You calculate your Zakah on that date each year based on your total qualifying wealth at that point.

Sadaqah

Voluntary charity. Unlike Zakah, sadaqah is not obligatory and has no minimum amount. It can be given to any person or cause at any time. In investment planning, sadaqah is commonly used for purification payments from portfolios.

Waqf

An Islamic endowment — the permanent dedication of an asset for charitable or religious purposes. Once established, a waqf cannot be sold, gifted, or inherited. The asset generates ongoing benefit for designated beneficiaries in perpetuity. Increasingly used as a vehicle for charitable estate planning. Read more: What Is Waqf? The Islamic Endowment Explained.

Islamic Estate Planning and Inheritance

Wasiyyah

An Islamic will or bequest. A Muslim may bequest up to one-third of their net estate to non-heirs (charities, friends, relatives who would not otherwise inherit) through a wasiyyah. The remaining two-thirds is distributed according to prescribed Shariah inheritance shares. Read more: What Is a Wasiyyah?

Miraath (Faraid)

Islamic inheritance law — the system of distributing a deceased Muslim’s estate among heirs according to fixed Shariah-prescribed shares. The system is detailed in Surah An-Nisa of the Quran. Read the complete guide: Islamic Inheritance in South Africa.

Asabah

Residual heirs in Islamic inheritance. After the fixed Quranic shares (dhul furudh) have been distributed, any remainder passes to residual heirs (asabah). Sons are the primary asabah; in their absence the role passes to other male relatives in a defined order of priority.

Awl

Proportional reduction. In cases where the fixed Shariah shares of all heirs add up to more than 100% of the estate, all shares are reduced proportionally. This ensures the total does not exceed the estate while maintaining relative ratios between heirs.

Radd

Redistribution. The opposite of awl — when prescribed shares add up to less than the total estate and there are no residual heirs, the surplus is redistributed back to the heirs proportionally.

Mahr

The mandatory gift a husband gives to his wife at the time of Islamic marriage. It is an exclusive financial right of the wife — her own property with no obligation to share it. Mahr can be paid at the time of marriage (prompt) or deferred, or a combination of both. It ranks as a debt against the husband’s estate. Read more: Mahr in Islamic Finance: A South African Planning Guide.

Hijab

In Islamic inheritance law, the exclusion of one heir by the presence of another. For example, a full brother is excluded by the presence of a son. Hijab can be complete (full exclusion) or partial (reduction in share). One of the most technically complex aspects of Islamic inheritance calculation.

South African Legal Terms in Islamic Finance

Community of Property (COP)

A South African marriage regime in which all assets and liabilities of both spouses are pooled into a joint estate. On the death of a COP spouse, the joint estate is first divided 50/50 before Islamic inheritance rules apply to the deceased’s half. Read more: Community of Property and Islamic Inheritance.

Antenuptial Contract (ANC)

A pre-marriage contract establishing that the couple will be married out of community of property. An ANC can include or exclude the accrual system. For Islamic estate planning, being married out of community of property with an ANC generally provides more clarity for inheritance distribution, as each spouse’s estate remains separate.

Intestate Succession

The legal process that applies when a person dies without a valid will. In South Africa, the Intestate Succession Act determines how the estate is distributed — and this does not follow Shariah inheritance rules. Every Muslim in South Africa should have a valid Islamic will to avoid intestate succession. Read more: What Happens When a Muslim Dies Without a Will.

Pension Funds Act Nomination

Under South African law, the trustees of a retirement fund have discretion to distribute a deceased member’s benefit, guided but not bound by the member’s nomination of beneficiaries form. Because retirement funds sit outside the estate, they do not automatically follow your Islamic will or Shariah inheritance shares. Reviewing your nomination form is a critical estate planning step. Read more: Retirement Funds and Islamic Inheritance.

Estate Duty

South African estate duty is a tax on the dutiable estate of a deceased person, levied above the abatement threshold. Estate duty is deducted from the estate before distribution, regardless of whether the estate is distributed under Islamic or civil law. Read more: Estate Duty and Islamic Inheritance.
