What is Shariah? — Islamic Law Framework Explained

Definition & Etymology

The word appears in the Quran in Surah al-Jathiyah (45:18): "Then We placed you on a clear path (shari'ah) of the matter, so follow it and do not follow the desires of those who do not know." This verse captures the essential nature of Shariah: it is a divinely mandated path, not an arbitrary human construction, and it calls for conscious, informed adherence rather than blind tradition.

Classical scholars distinguished between Shariah (the divine guidance itself) and fiqh (the human scholarly effort to understand and apply it). This distinction is crucial: Shariah is perfect and immutable; fiqh is scholarly, debated, and subject to revision as circumstances change and scholars develop new insights. When we speak of Shariah-compliant finance, we are always referring to compliance with the best current scholarly understanding — fiqh — not a claim to have perfectly captured divine will.

Sources of Shariah

Islamic jurisprudence (usul al-fiqh) identifies a hierarchy of sources from which Shariah rulings are derived:

Beyond these four primary sources, different schools of law also recognise secondary sources: istihsan (juristic preference), maslaha mursala (unrestricted public interest), urf (custom), istishab(presumption of continuity), and sadd al-dhara'i(blocking the means to harm). These secondary sources allow Islamic law to address novel situations while remaining grounded in scriptural principles.

Maqasid al-Shariah — The Objectives of Islamic Law

Imam al-Ghazali (1058-1111 CE) and later Imam al-Shatibi (1320-1388 CE) articulated the doctrine of Maqasid al-Shariah — the higher objectives that all Shariah rulings are designed to achieve. This framework is central to contemporary Islamic finance because it provides a purposive test: a financial transaction should not only comply formally with Shariah rules but should advance, or at least not undermine, these five essential values:

The maqasid framework has become increasingly important in contemporary Islamic finance scholarship. Critics of some conventional Islamic finance structures — such as certain Murabaha arrangements that mimic the cash flows of conventional loans — argue that they comply with the form of Shariah without advancing its objectives (particularly the preservation of wealth and justice). This debate drives ongoing reform and innovation in Islamic finance.

Shariah in Finance

The application of Shariah to financial transactions is governed by three primary prohibitions and a set of positive principles that shape the structure of Islamic financial products:

Alongside these prohibitions, Shariah mandates positive principles: risk-sharing (al-ghunm bil-ghurm), asset-backing (transactions should be linked to real economic activity), and fairness to all parties. For a comprehensive introduction to Islamic finance, see our Islamic Finance Basics guide.

Shariah Compliance

Shariah compliance in financial services operates at three levels: product screening, Shariah board oversight, and regulatory certification. For individual investors, compliance means ensuring investments pass Shariah screens — both sector exclusions (no alcohol, tobacco, conventional finance) and financial ratio tests. For institutions, it means maintaining an active Shariah Supervisory Board that pre-approves all products and conducts annual Shariah audits.

The leading global standard-setter, AAOIFI (Accounting and Auditing Organization for Islamic Financial Institutions), has published over 100 Shariah standards covering banking, capital markets, insurance (takaful), and Islamic investment funds. These standards are adopted or referenced by regulators in the UAE, Bahrain, Malaysia, Pakistan, Jordan, Sudan, and many other jurisdictions.
