This educational system instructed students on basic educational concepts, such as mathematics, writing, and reading. At the same time, it also taught things like obedience, duty to country, and general ethics. One of the main motivators for the Prussian education system, interestingly enough, was religious.

The name Usuli derives from the term Uṣūl al-fiqh (principles of jurisprudence). In Usuli thought, there are four valid sources of law: the Quran , hadith , ijma' and 'aql . Ijma' refers to a unanimous consensus. Aql, in Shia jurisprudence, is applied to four practical principles which are applied when other religious proofs are not applicable:  : 284-5 bara'at (immunity), ihtiyat (recommended precautions), takhyir (selection), and istishab (the presumption of continuity in the previous state).
