العروة الوثقى الزيدية - موقع إسلامي يهدف لتعريف الزائر بفكر وتراث المسلمين الزيدية

Answer:
The Zaidis legitimately affiliate themselves with Imam Zaid (peace be
upon him) by following him in the fundamentals and overarching
principles of religion. For a Zaidi, this affiliation is not a jurisprudential
affiliation like that of the Shafi‘i, Hanafi, Hanbali, or Maliki schools.
Historically, there existed the Hudawi school, affiliated with Imam al-
Hadi, and the Nasiri school, affiliated with Imam al-Nasir al-Utrush
(peace be upon them), yet both groups were considered part of
Zaidiyyah. Furthermore, every Imam, indeed every qualified jurist
(mujtahid) within Zaidiyyah, has his own specific school in matters of
jurisprudence. Yet, if you ask any of them about his school, he will
answer: “I am Zaidi.” The reason for this is that Zaidis prohibit taqlid
(uncritical imitation) in jurisprudential matters for those qualified for
independent reasoning (ijtihad). Therefore, each of their Imams, while
acknowledging the authority of those who preceded him, does not
permit himself to merely imitate them.
