أن لا يتضمن تغير حكم من أحكام النص
The analogy must not entail alteration of a legal ruling established by a text.
The first condition prevents direct contradiction. The second focuses on a subtler issue: an analogy must not reshape the scope or legal effect of the original textual command.
Principle in application: If a text attaches a specific ruling to a condition, one cannot use analogy to remove that condition and thereby transform the original rule.
This does not prohibit all interpretation. It prohibits an analogical extension whose necessary result is alteration of the established textual ruling.
