Q1. What is "Qiyas" in Islamic jurisprudence?
Answer: Analogical reasoning applied to new cases
Explanation: Qiyas is the fourth source of Islamic law and refers to analogical reasoning — extending an existing Sharia ruling to a new case that shares the same effective cause (illa). For example, the prohibition of wine is extended to all intoxicants by analogy.
