«لا يكون القياس في مقابلة النص»
Analogy must not stand against an explicit text.
Qiyas applies a text-grounded ruling to a new case; it is not a means of overruling the textual instruction. If the Qur’an or an established Sunnah text addresses a specific case, an analogy yielding an opposing result does not satisfy this condition.
The book illustrates the issue with a report about a pebble thrown during prayer and ablution. The underlying lesson is the priority of relevant textual evidence over conjectured similarity. The independent authentication and juristic evaluation of particular reports remains a separate question.
