The Classic Riba Hila
The clearest example of a hila in practice: riba (interest) is prohibited in Islamic law. Yet the economic need for deferred payment with compensation existed in medieval Muslim commercial life. The Hanafi solution (bay’ al-‘ina): sell an item to the buyer for cash, then buy it back from him at a higher deferred price. The net effect is a loan at interest, but the individual transactions are each valid sales.
Maliki and Hanbali scholars rejected this as a naked circumvention of the riba prohibition. The Hanafi position: the legal form is what the law evaluates, and each transaction is formally valid.
The Divorce Hila
A husband who pronounces three talaqs (irrevocable divorce) and then wants to remarry the same wife faces a legal obstacle: she must first marry another man, consummate that marriage, and be divorced again before the first husband may remarry her. The hila: arrange a muhallil (literally: one who makes lawful) — a man who contracts a temporary marriage with the sole intention of divorcing to allow the first husband to remarry. The Prophet specifically condemned the muhallil and the husband who uses him — providing the strongest textual basis for the anti-hila position.
The Schools’ Positions
- Hanafi: hiyal are generally permissible where formal legal validity is met
- Shafi’i: hiyal are permissible as long as they do not violate an established legal principle or constitute evident bad faith
- Maliki and Hanbali: hiyal are prohibited — the law considers intentions, not merely forms, and circumventing the spirit of a prohibition via technically permissible means violates the prohibition
