A concise book, "The Ultimate Goal and Hope in the Science of Usul" by Al-Amidi (d. 631 AH / 1233 AD).

"The Principles and Polemics" by Ibn al-Hajib (d. 646 AH / 1249 AD), and "The Refinement" by Shihab al-Din Abu al-Abbas Ahmad bin Idris al-Qurani (d. 684 AH / 1285 AD).

This science witnessed a more prosperous era after the Almohads, reaching a stage of maturity and innovation in the Maghreb. This is the stage represented by Abu Ishaq al-Shatibi in his renowned book.

If the study of the Quran, Hadith, and Usul had witnessed such prosperity, then it had a role in enriching the jurisprudential movement in the Maghreb and received the attention we mentioned.

And what was its fruit in adopting jurisprudence with the approach of establishing principles in deriving rulings? That is what we will try to explain below: The Jurisprudential Movement in the Almohad Era: Ibn Tumart and the Almohads after him, as previously indicated, aimed primarily through their attention to Usul to make knowledge of it a step towards establishing the branches. This endeavor bore some fruit, which can be observed in two aspects: The emergence of attempts at jurisprudential establishment, and the rise of a dialogue between the Malikis and the Zahiris. We will try below to explain the jurisprudential impact of Ibn Tumart's call through these two aspects.

A. Attempts at Jurisprudential Establishment: The Almohad rulers themselves were engaged in implementing jurisprudential establishment, either by directly undertaking it.
