Running a business according to Islamic ethics is not just about selling lawful products. The texts and the Islamic legal tradition attach great importance to the way trade is conducted: honesty in describing goods, keeping commitments, clear contracts, fair pay for employees and an equitable sharing of risk between partners.
This page presents these principles in practical terms for a business owner, partner or manager who wishes to apply them in a company operating within a Western legal framework.
The foundations of business ethics
Muslim jurists generally link business ethics to a few major principles:
- Truthfulness: not hiding a defect, not exaggerating a product's qualities, not tampering with weights and measures.
- Mutual consent: a contract is only valid if each party accepts it freely and with full knowledge.
- The prohibition of riba: interest on money loans, which the vast majority of scholars regard as forbidden.
- The prohibition of excessive gharar: major uncertainty about the subject matter, price or deadline makes a contract questionable.
- The prohibition of maysir: gains based on pure chance, such as gambling.
- Keeping commitments: honouring one's contracts, deadlines and debts.
These principles largely match modern commercial law (duty to inform, prohibition of misleading practices), which makes them easier to put into practice. In the UK, for instance, consumer protection law also prohibits misleading and unfair commercial practices.
Contracts: clarity and transparency
In practice, an ethically minded company makes sure its contracts specify the subject matter, price, deadlines and each party's responsibilities. A few points to watch:
- late-payment penalties in the general terms and conditions: some scholars recommend that they be given to charity rather than kept as a gain;
- selling goods you do not yet own, which Islamic law regulates through specific contracts such as salam or istisna;
- insurance and guarantee clauses, on which opinions differ.
If you are unsure about a structure, the opinion of a scholar or a specialist board is preferable to a personal interpretation.
Partnership models: musharaka and mudaraba
Musharaka
In a musharaka, several partners contribute capital and sometimes work. Profits are shared in a proportion agreed in advance, while losses are generally borne in proportion to the capital contributed. This arrangement resembles many ordinary companies, so it can be adapted within a French SAS or SARL, or a UK limited company, through the articles of association and a shareholders' agreement.
Mudaraba
A mudaraba brings together a capital provider and a partner who contributes expertise and management. Profit is shared according to a ratio set in advance; in the event of a financial loss without fault on the manager's part, the capital provider bears it, while the manager loses the value of their work. This model inspires certain investment and asset management contracts.
What to avoid
Scholars usually regard as problematic a guaranteed fixed return on capital invested in a risky activity, because it turns the partnership into an interest-bearing loan.
Relations with employees
The tradition stresses paying wages promptly and fairly, clarity about tasks and respect for employees' dignity. Under French law, these requirements match the employer's obligations: a written contract, regular payment, health and safety, non-discrimination. A Muslim business owner remains bound by employment law, particularly on neutrality and adjustments: see our page on employment law and religion.
Funding and cash flow
Running a business without resorting to interest requires planning ahead: building up reserves, favouring equity contributions, negotiating terms with suppliers, and using leasing or Islamic finance products where available. These solutions are presented in our overview of Islamic finance. When part of the income comes from a doubtful source, the question of purification is dealt with on the page about accounting for mixed income.
Governance and compliance
A company that claims an ethical identity benefits from formalising its commitments: a purchasing charter, a supplier policy, checks on certifications, a complaints procedure. ISO management standards (quality, anti-bribery) provide recognised frameworks, and SMIIC standards cover halal requirements. Combating fraud and bribery is both a religious and a legal duty; our page on fraud and corruption covers it in detail.
Relations with suppliers and customers
Business ethics also apply upstream and downstream. With suppliers, they call for paying within the agreed terms, not using a dominant position to impose unfair conditions and checking the origin of the products bought. French law points the same way by regulating payment terms between businesses and restrictive competitive practices.
With customers, the tradition condemns misrepresenting goods, hoarding stock to drive up prices and pressure selling. A clear returns policy, precise quotes and invoices without hidden charges put these principles into practice. For a business owner, they are also commercial arguments: a reputation for honesty builds customer loyalty and attracts staff who share these values. Sectors where these issues are most visible, such as import-export, call for particular vigilance over certificates and intermediaries.
Business owner's checklist
- Are my products and services lawful, and are my sources of income identified?
- Are my contracts clear about the subject matter, price and deadlines?
- Do my partners genuinely share the risk?
- Are my employees paid on time and treated fairly?
- Can my marketing claims be verified?
- Have I identified a scholar or competent adviser for delicate questions?
