KembaraXtra-Islamic Finance – 50 Examples of Istishab (Presumption of Continuity)

Introduction

Istishab is a principle of Islamic jurisprudence that means presumption of continuity. It is applied when there is uncertainty: the law assumes that the previously established state of affairs continues until proven otherwise.

• It avoids unnecessary doubt.
• It prevents arbitrary rulings.
• It safeguards rights and obligations until clear evidence changes them.

Types of Istishab:

1. Istishab al-ʿAdam al-Asli – presumption of original non-existence (e.g., a debt does not exist unless proven).
2. Istishab al-Ibahah – presumption of permissibility (things are halal unless proven haram).
3. Istishab al-Hukm – presumption that a ruling continues until there is new evidence.
4. Istishab al-Wasf – presumption of attributes continuing (e.g., purity of water unless shown otherwise).

In Islamic finance, Istishab prevents unfair burdens and ensures continuity of contracts, debts, and property rights until proven otherwise.
