LessonsLegal Cause, Effective Cause and ConditionQuiz

ثم السبب قد يقام مقام العلة عند تعذر الاطلاع على حقيقة العلة.
A sabab may be treated as standing in for an effective cause when the true cause is not reliably ascertainable.

This does not authorize arbitrary substitution. Law may employ a recognizable and reasonably determinate outward circumstance because the underlying private or variable state is not consistently knowable.

Three examples follow: sleep as a proxy for possible ritual impurity, valid private seclusion in certain marriage consequences, and travel as a legal proxy for hardship. Each substitution has a defined sphere; it does not make the proxy identical to the underlying reality in every respect.
