What is the difference between ʿaqīdah and fiqh?

ʿAqīdah is what a Muslim believes. Fiqh is what a Muslim does. The classical scholars kept them distinct because confusing them leads to two different kinds of error — believing the wrong thing, or doing the wrong thing on the basis of a belief you didn't examine.

10 passages from 6 books in the library

ʿAqīdah is what a Muslim believes; fiqh is what a Muslim does. The classical scholars kept the two sciences distinct and warned against either disparaging the other — "a language teacher should not disparage jurisprudence, nor should a jurisprudence teacher dismiss" the rest. Imam al-Ghazali notes how some later "confined the name of jurisprudence" to legal rulings and "called it fiqh." On the side of belief, he observes that for most people "belief close to certainty" suffices, and that "the law only required simple belief from the early Arabs, not investigation or evidence" — creed and law each serving a different need.

Where the answer comes from

The classical approach.

These passages are drawn from 6 books by Imam al-Ghazali and Ibn Battuta — part of the classical Sunni tradition that carries over a thousand years of reflection on the Qurʾān, the authentic Sunnah, and the consensus of the early community. Nothing below is a paraphrase. The words are the scholars' own, translated from the original Arabic manuscripts.

Read them closely. If a passage doesn't sit right, open the full book in the library and listen to the chapter around it. Context in the classical tradition is everything.
