Qiyas

Qiyas is an Islamic legal method used to derive new rulings by applying principles from established texts to situations not explicitly addressed in the Quran or Hadith. It involves comparing a new case to a similar, known case based on shared underlying reasons (known as 'illah' or 'effective cause'). This process helps scholars maintain consistency and adapt religious laws to new circumstances, ensuring that the principles remain relevant while grounded in core Islamic teachings. Qiyas is an important tool alongside other methods like direct textual evidence and consensus for comprehensive Islamic jurisprudence.
