«لا يكون حكم الأصل ما لا يعقل معناه»
The original ruling must not be one whose operative rationale cannot be understood.

Analogy requires a transferable cause. If a ruling is exceptional or specifically devotional and no suitable common rationale can be identified, there is no basis for extending it to another case.

The textbook uses the exceptional juristic example of ablution with date infusion (nabidh al-tamr).

This illustrates the rule rather than presenting every school’s practical fatwa.
