Answered by Shaykh Faraz Rabbani
Could you please tell me what is qiyas?
I hope you’re doing well, Insha Allah.
Qiyas refers to legal analogy. It is to derive the religious verdict for an issue that doesn’t have a specific ruling in the Quran or Sunna through a shared legal basis (‘illa) from established texts. [Haskafi/Nasafi, Ifadat al-Anwar Sharh al-Manar; others]
For more details, refer to reliable introductions to Islamic Law, or the Level One course on How Islam works at SeekersGuidance: How Islam Works: What is Religion, and How It Is Preserved, Transmitted, and Interpreted
Legal Analogy Is Well-Established and Accepted
All four schools of mainstream Islam affirm the legal basis of analogy (qiyas). [Ansari, Lubb al-Usul; Ibn al-Humam, Tahrir]
It is only a minority of Literalists (dhahiris) who denied it. Regarding them, Abu Bakr al-Jassas (Allah have mercy upon him)said, “Their differences [in matters of method] are not of consequence…” [Jassas, al-Fusul fi’l Usul; also related from Juwayni, Nawawi, and others]
The Wisdom and Benefit of Analogy (Qiyas)
Legal analogy allows jurists (fuqaha) to extend the teachings of the Quran and Sunna to new and changing issues, with precision and caution. However, this is only done by those qualified–the mujtahid. [Adib Salih, Tafsir al-Nusus]
And Allah is the giver of success and facilitation.
