Fiqh al-Kafalah (فِقهُ الكَفَالَة — Jurisprudence of Guarantee/Suretyship; one of the foundational contracts of Islamic commercial law alongside murabaha, ijara, and musharaka; kafalah is: a contract by which a third party [kafil — the guarantor] undertakes responsibility for the obligation of another person [makful 'anhu — the principal debtor] toward a fourth party [makful lahu — the creditor/beneficiary]; the Quranic basis: 12:72 in the Joseph story when the king's herald says 'I will be its guarantor' [ana bihi za'im]; the Prophetic basis: the hadith 'al-za'im gharim' [the guarantor is liable]; the kafil's liability is additional to, not replacing, the original debtor's liability [in the majority view]; four main types: kafalah al-nafs [guarantee of person — ensuring the debtor appears], kafalah al-mal [guarantee of property/debt], kafalah al-dayn [guarantee of debt payment], kafalah al-ayn [guarantee of a specific asset's return]) is the instrument underlying modern Islamic letters of guarantee and performance bonds.

The Core Structure

A kafalah contract involves three parties:

When the principal debtor fails to perform, the creditor can demand performance from the guarantor. This is additive liability in most schools: the creditor now has two parties to pursue, not just one.

Modern Applications

Letters of Guarantee: Banks issue guarantees on behalf of clients (for contractors, importers, etc.) — the bank is the kafil. The Islamic structure requires that the bank issue the guarantee in return for a fee, without charging interest on the contingent liability.

Performance Bonds: Construction and procurement contracts require guarantees of performance. An Islamic bank as kafil provides a performance bond for a fee (ujra), not as a loan.

AAOIFI Standard 5 covers kafalah in detail and permits fees (ujra) for the service of guarantee, distinguishing them from riba since the fee is for the service of issuing the guarantee, not for the passage of time.
