LessonsQiyas: Definition, Authority, Five Conditions, Effective Cause and TypesQuiz

Before accepting a proposed analogy, ask five questions:
1. Does it conflict with an applicable text?
2. Would it alter a textually established ruling?
3. Does the original ruling have an intelligible effective cause?
4. Is the aim a legal ruling rather than a new lexical label?
5. Has the new case itself already been settled expressly?

Passing these screening questions does not prove every analogy. The next task is to establish the correct ‘illah and its presence in the new case, rather than relying on incidental similarity.
